Click on OK to shut the “choose included entries dialog” and OK on the configure palette. Save the palette as it's advised and by this fashion we've created a customized object palette designed particularly for our wants. four.2.three Configuring the site visitors It's a good suggestion to outline the profiles and purposes that will likely be utilized by the LAN earlier than we start setting up the community. We outline the profiles within the profile definition object and purposes within the utility definition object. A profile is utilized to a workstation, server, or LAN. It specifies the purposes utilized by a specific group of customers. An utility could also be any of the frequent purposes (electronic mail, file switch) or a customized utility you outline. Eight frequent (“normal”) purposes are already outlined: Database Entry, E-mail, File Switch, File Print, Telnet Session, Video conferencing, Voice over IP Name, and Internet Looking. To configure the Software Configuration object drag an Software Config object to the venture workspace. Proper-click on it and choose Edit Attributes. Set the title attribute to Software Configuration and alter the Software Definitions attribute to Default by clicking within the attribute’s Worth column and deciding on Default from the pop-up record. Choosing Default configures the applying definition object to have the eight normal purposes talked about earlier. Shut the Attributes dialog field. To Configure the Profile Configuration Object Drag a Profile Configuration object from the article palette to the venture workspace. Proper-click on it and choose Edit Attributes. Set the title attribute to Profile Configuration and alter the Profile Configuration attribute by clicking in its Worth column and deciding on Edit… from the drop-down menu. Change the variety of rows to 1, title the brand new profile LAN Shopper and alter the Operation Mode to Simultaneous. Then click on within the profile’s Begin Time (seconds) cell to open the “Begin Time” Specification dialog field and choose fixed from the Distribution Identify pull-down menu. Set Imply End result to 100, then click on OK. The Begin Time attribute has a price of fixed (100). Now shut the Begin Time Specification dialog field by clicking OK.

Once we chosen Default because the worth for the Software Definitions attribute on this object, we enabled this record of purposes. Notice that the record contains 16 entries, a heavy and light-weight model for every of the eight normal purposes. Set the Begin Time Offset to Uniform (zero, 300), confirm that the Distribution Identify is uniform, set the Minimal End result to zero and the Most End result to 300. Click on OK to shut the Functions Desk dialog field and OK to shut the Profile Configuration Desk, then click on OK once more to shut the Attributes dialog field. four.2.four Creating the topology We are going to now create the next community inside the world we've ready for it. Now that we've arrange the state of affairs and the site visitors inside it we're prepared to start setting up the WAN. As a result of the community incorporates 4 equivalent subnets, we will create the primary subnet in Portsmouth, with its nodes inside it, after which copy the subnet to Glasgow and Manchester. We can even copy it to London and modify it additional. To create the Portsmouth subnet, click on on the subnet icon within the object palette, drag it to the workspace and right-click to show off node creation. Now double-click on the Portsmouth subnet and choose View – Background – Set Properties…. Notice that the show grid is in levels, which isn't acceptable for an workplace. Set the items to Meters, uncheck the Seen checkbox for Satellite tv for pc orbits and confirm that Drawing is ready to Dashed. Set the division to 10 and eventually click on the Shut button. Modelling the community doesn't require modelling the exact nature of every node in every subnet, so we can characterize the subnets with a LAN mannequin. To create a LAN mannequin, place a 10BaseT_LAN within the workspace. Proper-click on it and select Edit Attributes. We are able to change a LAN mannequin’s attributes so that it precisely represents a community with a sure variety of workstations and a specific site visitors profile. To characterize one of many workplaces change the LAN mannequin’s title attribute to Office_LAN after which select Edit… for the Software: Supported Profiles attribute. In there change the variety of rows to 1 after which change the Profile Identify to LAN Shopper and click on OK. Now this LAN will use the LAN Shopper profile we created earlier. This profile contains the File Switch (Heavy) utility. The LAN will ship site visitors that fashions heavy FTP use. Lastly, click on OK to shut the Edit Attributes dialog field. We have now now modelled a 10 workstation LAN contained in the Portsmouth subnet. This single object is equal to a 10-workstation star topology LAN. As a result of this LAN mannequin consists of workstations and hyperlinks solely, it should be linked to a router. The router can then be linked to different routers within the community. To create a router drag a BN_BLN_4s_e4_f_sl8_tr4 node (a Bay Networks router) from the article palette to the workspace close to the Office_LAN node. Identify the brand new node Router and join the router and the Office_LAN node with a 10BaseT hyperlink. Proper-click to show off hyperlink creation. The Portsmouth subnet is now configured. As a result of the subnets within the different cities are equivalent, you possibly can copy the Portsmouth subnet and place it appropriately. To repeat the subnet return to the mum or dad subnet view by clicking on the Go to Guardian Subnetwork button (you may as well proper click on on the workspace to deliver up the workspace pop-up menu, then select Go to Guardian Subnetwork from the menu). Change the subnet’s title to Portsmouth by deciding on Set Identify from the article’s pop-up menu. Choose the subnet and press +c after which paste the subnet to every of the three completely different cities by urgent +v. Rename every metropolis’s subnet appropriately and join every subnet to the London workplace utilizing the PPP_DS0_int hyperlink kind the article palette. Draw a PPP_DS0 hyperlink from London to Portsmouth. A Choose Nodes dialog field seems asking which nodes in every subnet are to be endpoints of the hyperlink. Select the corresponding routers of every subnet and click on OK to determine the hyperlink. To finish the community, the primary workplace in London must have a swap and a server added to it. To configure the community in London double-click on the London subnet to enter its subnet view. Place one swap and one ethernet_server node within the workspace. Rename the node to Swap and the ethernet_server to FTP. Proper click on and choose Edit Attributes on the FTP server and within the Software: Supported companies choose edit and add one row in the desk. Select File Switch (Heavy) from the menu. Click on okay and shut the attributes of the server. Now there's a server inside the community configured to help the applying utilized by it. Lastly join the router and the server to the swap with 10BaseT hyperlinks and when completed shut the article palette. four.three Simulation Earlier than we run the simulation, we have to setup statistics stories that we're going to produce graphically.

[2 Mark] Job 2: AS/Web Design and simulation (20%) Introduction You'll design and develop a simulation for an inter-connection between 5 Ass utilizing native desire attribute. Setting out the Community Parts We're going to set out a reasonably difficult community to display enterprise stage/inter-connection between 5 completely different ASs. The mannequin and the related ASs are proven beneath. In an effort to make it straightforward to understand we're going to use the “Logical Subnet” part. This design course of permits us to have a number of layers, including comprehension and visualisation of what could also be a really difficult community. 5 of those needs to be set out on the community canvas as proven beneath. Should you double click on on every of those subnets then you'll be taken into the subnet. To get out of the subnet you have to proper click on and choose “Go To Guardian Subnet”. I recommend placing community elements into every of the autonomous programs as proven beneath. AS11 AS22 AS33 AS44 AS55 As soon as the entire elements have been positioned into the logical subnets you possibly can join them collectively by connecting a cable between the 2 subnets. This can current you with a selection of what elements to attach as proven beneath. Please be sure that you join the routers to at least one one other accurately (demonstrated within the community diagram). Including Visitors It's best to add the applying config and profile config nodes. Arrange two purposes, HTTP:Picture Looking and FTP: Excessive Load (however you have to edit the inter-request time to “exponential(36)” as a substitute of “exponential(360)”). It's best to arrange one profile that utilises these purposes concurrently. It's best to arrange the LAN in AS11 to make use of that profile. It's best to then arrange the server in AS55 to help HTTP and the server in AS44 to help FTP. Configure BGP It's best to configure BGP between every AS (please use the steerage supplied in ISP 1 lecture to obtain this). The inner connection between the border routers in AS22 and AS33 mustn't use BGP, however ought to use RIP or OSPF. Configure Visitors We are going to now carry out some site visitors engineering, you must duplicate your BGP state of affairs and name the duplication “BGP_Local_pref”. Implied within the mannequin is a peering relationship between AS11-AS22, AS22-AS33 and AS33-AS44. We're going to power the FTP site visitors destined to AS44 (truly it is going to be all site visitors destined for AS44) by the trail AS11-AS22-AS33-AS44. In an effort to do that we'll set the native desire of the route by AS22 to a low worth, thereby forcing the site visitors to undergo AS22-AS33 (the native desire is, by default, set as 100 minus the variety of AS hops). Experiment 1 1. It's best to confirm that each HTTP site visitors and FTP site visitors is flowing within the community and you must confirm the route that the site visitors is taking. (5%) Experiment 2 1. It's best to confirm that each HTTP site visitors and FTP site visitors remains to be flowing within the community and you must confirm the route that the site visitors is taking. (three%) 2. It's best to confirm the BGP is getting used accurately to replace routing tables. (2%) Within the border router of AS11 we have to arrange a route map as proven beneath. Should you increase the IP- >IP Routing Parameters you get entry to the Route Map Configuration. This route map then must be utilized to the route acquired from the suitable neighbour. As proven beneath, it's utilized to the route acquired from AS55 to 11 (so by setting the native desire to 10 this route turns into much less fascinating for site visitors destined to AS44). Add a reputation Add AS Path Incorporates 33 Set to Native Desire You want to edit the IP Routing Parameters->BGP Parameters. Notice that it's configured for the routes coming from AS55. Add Route Map 1 for routes coming into this AS. Experiment three 1. It's best to confirm that the following hop deal with within the routing desk of AS11_ASBR for server in AS44 has now modified. (5%) 2. You also needs to confirm that the quantity of site visitors between AS11 and AS22 has modified (and confirm why local_pref is known as an “out-bound” site visitors engineering approach). (5%) Report half three (20%) (Please use the report template supplied which might be present in Moodle) Full every experiment specified within the blue field, as proven beneath: You will need to be sure that the minimal that you just file in your report is the proof (screenshots) that you've accomplished the duty with transient clarification to every. Ideally you need to doc issues, the way you recognized issues and the way you overcame these issues. ALL solutions MUST be primarily based on OpNet simulations. Web sourced outcomes will NOT be awarded any marks! Experiment 1 1. It's best to confirm that each HTTP site visitors and FTP site visitors is flowing within the community and also you ought to confirm the route that the site visitors is taking. (5%) Experiment 2 1. It's best to confirm that each HTTP site visitors and FTP site visitors remains to be flowing within the community and you must confirm the route that the site visitors is taking. (three%) 2. It's best to confirm the BGP is getting used accurately to replace routing tables. (2%) Experiment three 1.

In that desk change the variety of rows to 1, set the title to File Switch (Heavy) by clicking within the cell and deciding on the applying from the pop-up menu. The contents of this pop-up menu are managed by the Functions Configuration object. Once we chosen Default because the worth for the Software Definitions attribute on this object, we enabled this record of purposes. Notice that the record contains 16 entries, a heavy and light-weight model for every of the eight normal purposes. Set the Begin Time Offset to Uniform (zero, 300), confirm that the Distribution Identify is uniform, set the Minimal End result to zero and the Most End result to 300. Click on OK to shut the Functions Desk dialog field and OK to shut the Profile Configuration Desk, then click on OK once more to shut the Attributes dialog field. four.2.four Creating the topology We are going to now create the next community inside the world we've ready for it. Now that we've arrange the state of affairs and the site visitors inside it we're prepared to start setting up the WAN. As a result of the community incorporates 4 equivalent subnets, we will create the primary subnet in Portsmouth, with its nodes inside it, after which copy the subnet to Glasgow and Manchester. We can even copy it to London and modify it additional. To create the Portsmouth subnet, click on on the subnet icon within the object palette, drag it to the workspace and right-click to show off node creation. Now double-click on the Portsmouth subnet and choose View – Background – Set Properties…. Notice that the show grid is in levels, which isn't acceptable for an workplace. Set the items to Meters, uncheck the Seen checkbox for Satellite tv for pc orbits and confirm that Drawing is ready to Dashed. Set the division to 10 and eventually click on the Shut button. Modelling the community doesn't require modelling the exact nature of every node in every subnet, so we can characterize the subnets with a LAN mannequin. To create a LAN mannequin, place a 10BaseT_LAN within the workspace. Proper-click on it and select Edit Attributes. We are able to change a LAN mannequin’s attributes so that it precisely represents a community with a sure variety of workstations and a specific site visitors profile. To characterize one of many workplaces change the LAN mannequin’s title attribute to Office_LAN after which select Edit… for the Software: Supported Profiles attribute. In there change the variety of rows to 1 after which change the Profile Identify to LAN Shopper and click on OK. Now this LAN will use the LAN Shopper profile we created earlier. This profile contains the File Switch (Heavy) utility. The LAN will ship site visitors that fashions heavy FTP use. Lastly, click on OK to shut the Edit Attributes dialog field. We have now now modelled a 10 workstation LAN contained in the Portsmouth subnet. This single object is equal to a 10-workstation star topology LAN. As a result of this LAN mannequin consists of workstations and hyperlinks solely, it should be linked to a router. The router can then be linked to different routers within the community. To create a router drag a BN_BLN_4s_e4_f_sl8_tr4 node (a Bay Networks router) from the article palette to the workspace close to the Office_LAN node. Identify the brand new node Router and join the router and the Office_LAN node with a 10BaseT hyperlink. Proper-click to show off hyperlink creation. The Portsmouth subnet is now configured. As a result of the subnets within the different cities are equivalent, you possibly can copy the Portsmouth subnet and place it appropriately. To repeat the subnet return to the mum or dad subnet view by clicking on the Go to Guardian Subnetwork button (you may as well proper click on on the workspace to deliver up the workspace pop-up menu, then select Go to Guardian Subnetwork from the menu). Change the subnet’s title to Portsmouth by deciding on Set Identify from the article’s pop-up menu. Choose the subnet and press +c after which paste the subnet to every of the three completely different cities by urgent +v. Rename every metropolis’s subnet appropriately and join every subnet to the London workplace utilizing the PPP_DS0_int hyperlink kind the article palette. Draw a PPP_DS0 hyperlink from London to Portsmouth. A Choose Nodes dialog field seems asking which nodes in every subnet are to be endpoints of the hyperlink. Select the corresponding routers of every subnet and click on OK to determine the hyperlink. To finish the community, the primary workplace in London must have a swap and a server added to it. To configure the community in London double-click on the London subnet to enter its subnet view. Place one swap and one ethernet_server node within the workspace. Rename the node to Swap and the ethernet_server to FTP. Proper click on and choose Edit Attributes on the FTP server and within the Software: Supported companies choose edit and add one row in the desk. Select File Switch (Heavy) from the menu. Click on okay and shut the attributes of the server. Now there's a server inside the community configured to help the applying utilized by it. Lastly join the router and the server to the swap with 10BaseT hyperlinks and when completed shut the article palette. four.three Simulation Earlier than we run the simulation, we have to setup statistics stories that we're going to produce graphically. Proper click on anyplace on the workspace. Choose from the pop-up menu, Select Select Particular person Statistics and edit them in order that the next solely is ready to ON (with a inexperienced tick or dot): World Statistics – Ftp – Obtain Response time (sec) Hyperlink Statistics – point-to-point – utilization -> Press OK to shut the select outcomes dialog. We are actually able to configure and run the simulation. Within the DES menu select Configure/Run Discrete Occasion Simulation. Set the period to 1 hour(s) within the frequent attributes tab. Press RUN for the simulation to begin. four.three.1 Outcomes To view the graph outcomes, proper click on anyplace on the workspace and from the menu select View Outcomes. From World Statistics, choose Ftp – Obtain Response Time (sec) and click on present. The plot will seem in a brand new window in your display screen. You can even manipulate the way in which the plot seems on the display screen with the intention to make it simpler so that you can perceive what is going on. Proper click on on the Ftp plot and choose Edit Graph Properties. Within the new window that seems change the draw fashion from “discrete” to “bar” and press apply. The graph ought to change and the factors ought to turn into bars. Press OK. To print the specified graphs you possibly can choose to create an online report that may include solely the graphed outcomes that you just need. Leaving the outcomes home windows open go to the primary Modeller menu and from the DES select Outcomes – Generate net report (you possibly can select between “Embrace graphed outcomes” or “Embrace all outcomes”). Identify this report Graphs and click on OK. A brand new net report has now been generated and also you can see it in DES – Outcomes – Launch Final Internet Report. A browser window opens. Click on on Report: Graphed Outcomes on the highest left nook after which click on on the brand new hyperlink that seems below it that incorporates the names of the chosen graphs, to view them. Click on on the graph as soon as with the intention to choose the body containing the graph in any other case you'll print one thing irrelevant and waste your print quota!!! Select Print from browser’s important menu and the plot will likely be despatched to printer lja (change it to ljb relying on the printer queues on the time of the lab). four.four A number of Eventualities We are going to now create a second state of affairs with 50% greater loading to check the efficiency of the community. Go to Eventualities – Duplicate Situation and title the brand new scenario2. Press CTRL-R and the Configure discrete occasion simulation window seem. Go to the World Attributes tab and scroll right down to the top till you discover the Visitors scaling issue and by single clicking on it change it to 1.5. Additionally change the Visitors scaling mode to all site visitors. four.four.1 Operating the simulation Now we have to configure and run each the situations of the venture with the intention to get the outcomes and examine them. From the Predominant Menu go to Eventualities – Handle situations. The handle situations window opens. Within the Outcomes row click on as soon as in each state of affairs and select . Below sim period sort 1 for all situations. Below Time Models select hour(s) We are actually able to run the simulation by clicking OK within the backside proper nook of the window. four.5 Evaluating outcomes Create a third state of affairs by duplicating the second and this time attempt by altering the hyperlink capability between the nodes to attain roughly the identical utilization as in state of affairs 1 however with out altering in any respect the site visitors as outlined within the Software Configuration Utility block. When you obtain that, create a 4th state of affairs by duplicating the third (we have to use the hyperlinks used within the third) and after taking down the site visitors scaling issue again to 1 attempt to enhance the site visitors within the Software Configuration Utility block to attain the similar utilization as within the third state of affairs. Report half 1 (Please use the report template supplied which might be present in Moodle) ALL solutions MUST be primarily based on OpNet simulation. Web sourced outcomes will NOT be awarded any marks! 1. Is it essential in community design to know how you can simulate multiple state of affairs for the one community? Briefly clarify why. [2 Mark] 2. When configuring the site visitors, you have to setup an merchandise known as, “Imply end result”, how do you discover and set it? [2 Mark] three. Clarify what components aside from community site visitors loading & message transit delay occasions would more likely to have an effect on community efficiency? [2 Mark] four. Which of the next configuration you have to do first? a. Software configuration b. Profile configuration c. Doesn’t matter [1 Mark] 5. How do you impose site visitors hundreds? [2 Mark] 6. What's the important distinction between utility configuration and profile configuration in OPNET? [2 Mark] 7. If the simulation is profitable, what number of entries needs to be logged in DES Log? [1 Mark] eight. How do you get outcomes to check greater than two situations? [2 Mark] 9. After two profitable simulations, you now have two units of outcomes, one for the preliminary work and one for the 50% greater loaded work, please connect one graph from every state of affairs and briefly talk about the variations between two outcomes. [4 Marks] 10. Contemplating the pc community introduced within the simulation is a nationwide financial institution, put together a full tradeoff desk and talk about every technical objective. [12 Marks] Coursework 2: Half 2 ISP & Enterprise Community (30%) Job 1: Mapping AS/Web Relationships (10%) Introduction You'll accumulate and examine the data that's freely accessible relating to the logical connectivity between autonomous programs. Amassing Information It's best to establish the IP deal with of the machine that you're at the moment sitting on. Put this IP deal with into RIPE Database question (https://apps.db.ripe.internet/search/question.html). Determine the ASN (autonomous system quantity) primarily based on the outcomes from you RIPE Database question. Go to https://stat.ripe.internet/ and lookup the connectivity of that ASN and discover a record of the autonomous programs that that AS is linked to. ALL solutions MUST be primarily based on RIPE Database and UCLA websites. Another Web sourced outcomes will NOT be awarded any marks! Report half 2 (10%) (Please use the report template supplied which might be present in Moodle) 1. Select one stub, one massive ISP and one tier-1 ISP and notice their ASN and IP prefix commercial.. [3 Mark] 2. Notice how they're linked (the variety of connections). [1 Mark] three. Go to https://stat.ripe.internet/ and sort in every of the ASNs and notice the prefix dimension distribution, transits distribution and the AS path size to the collectors. [3 Mark] four. Go to again to https://stat.ripe.internet/ or http://warmth.cs.ucla.edu and hint three hops away from the AS that you're at the moment in. [1 Mark] 5. Carry out one or many traceroutes to establish the variety of hops to an IP deal with within the AS three hops away out of your present AS. [2 Mark] Job 2: AS/Web Design and simulation (20%) Introduction You'll design and develop a simulation for an inter-connection between 5 Ass utilizing native desire attribute. Setting out the Community Parts We're going to set out a reasonably difficult community to display enterprise stage/inter-connection between 5 completely different ASs. The mannequin and the related ASs are proven beneath. In an effort to make it straightforward to understand we're going to use the “Logical Subnet” part. This design course of permits us to have a number of layers, including comprehension and visualisation of what could also be a really difficult community. 5 of those needs to be set out on the community canvas as proven beneath. Should you double click on on every of those subnets then you'll be taken into the subnet. To get out of the subnet you have to proper click on and choose “Go To Guardian Subnet”. I recommend placing community elements into every of the autonomous programs as proven beneath. AS11 AS22 AS33 AS44 AS55 As soon as the entire elements have been positioned into the logical subnets you possibly can join them collectively by connecting a cable between the 2 subnets. This can current you with a selection of what elements to attach as proven beneath. Please be sure that you join the routers to at least one one other accurately (demonstrated within the community diagram). Including Visitors It's best to add the applying config and profile config nodes. Arrange two purposes, HTTP:Picture Looking and FTP: Excessive Load (however you have to edit the inter-request time to “exponential(36)” as a substitute of “exponential(360)”). It's best to arrange one profile that utilises these purposes concurrently. It's best to arrange the LAN in AS11 to make use of that profile. It's best to then arrange the server in AS55 to help HTTP and the server in AS44 to help FTP. Configure BGP It's best to configure BGP between every AS (please use the steerage supplied in ISP 1 lecture to obtain this). The inner connection between the border routers in AS22 and AS33 mustn't use BGP, however ought to use RIP or OSPF. Configure Visitors We are going to now carry out some site visitors engineering, you must duplicate your BGP state of affairs and name the duplication “BGP_Local_pref”. Implied within the mannequin is a peering relationship between AS11-AS22, AS22-AS33 and AS33-AS44. We're going to power the FTP site visitors destined to AS44 (truly it is going to be all site visitors destined for AS44) by the trail AS11-AS22-AS33-AS44. In an effort to do that we'll set the native desire of the route by AS22 to a low worth, thereby forcing the site visitors to undergo AS22-AS33 (the native desire is, by default, set as 100 minus the variety of AS hops). Experiment 1 1. It's best to confirm that each HTTP site visitors and FTP site visitors is flowing within the community and you must confirm the route that the site visitors is taking. (5%) Experiment 2 1. It's best to confirm that each HTTP site visitors and FTP site visitors remains to be flowing within the community and you must confirm the route that the site visitors is taking. (three%) 2. It's best to confirm the BGP is getting used accurately to replace routing tables. (2%) Within the border router of AS11 we have to arrange a route map as proven beneath. Should you increase the IP- >IP Routing Parameters you get entry to the Route Map Configuration. This route map then must be utilized to the route acquired from the suitable neighbour. As proven beneath, it's utilized to the route acquired from AS55 to 11 (so by setting the native desire to 10 this route turns into much less fascinating for site visitors destined to AS44). Add a reputation Add AS Path Incorporates 33 Set to Native Desire You want to edit the IP Routing Parameters->BGP Parameters. Notice that it's configured for the routes coming from AS55. Add Route Map 1 for routes coming into this AS. Experiment three 1. It's best to confirm that the following hop deal with within the routing desk of AS11_ASBR for server in AS44 has now modified. (5%) 2. You also needs to confirm that the quantity of site visitors between AS11 and AS22 has modified (and confirm why local_pref is known as an “out-bound” site visitors engineering approach). (5%) Report half three (20%) (Please use the report template supplied which might be present in Moodle) Full every experiment specified within the blue field, as proven beneath: You will need to be sure that the minimal that you just file in your report is the proof (screenshots) that you've accomplished the duty with transient clarification to every. Ideally you need to doc issues, the way you recognized issues and the way you overcame these issues. ALL solutions MUST be primarily based on OpNet simulations. Web sourced outcomes will NOT be awarded any marks! Experiment 1 1. It's best to confirm that each HTTP site visitors and FTP site visitors is flowing within the community and also you ought to confirm the route that the site visitors is taking. (5%) Experiment 2 1. It's best to confirm that each HTTP site visitors and FTP site visitors remains to be flowing within the community and you must confirm the route that the site visitors is taking. (three%) 2. It's best to confirm the BGP is getting used accurately to replace routing tables. (2%) Experiment three 1. It's best to confirm that the following hop deal with within the routing desk of AS11_ASBR for server in AS44 has now modified. (5%) 2. You also needs to confirm that the quantity of site visitors between AS11 and AS22 has modified (and confirm why local_pref is known as an “out-bound” site visitors engineering approach).
