Global Knowledge-Cisco - (Page 15) MPLS ENT – Enterprise Networks over Service Provider MPLS Course 5942 A Global Knowledge exclusive: Learn to connect enterprise networks with MPLS-based service providers. Course Description As MPLS-based networks become more competitively priced, migrating from Frame Relay connections to MPLS backbones makes sense. To optimize and take full advantage of the MPLS-based backbone, you must understand the full implications of the migration including BGP requirements and Quality of Service (QoS) issues. In this course, discover and explore the concepts and requirements of an enterprise network that is migrating from Frame Relay connections to an MPLS-based service provider. You’ll get an overview of BGP focusing on enterprise network requirements. Then, you’ll cover MPLS/VPN and QoS and examine how the MPLS network topology impacts the Enterprise QoS SLAs. Hands-On Labs Lab 1: Network Setup Establish physical connectivity between the student routers, configure IP addressing, enable an Interior Routing Protocol, and verify routing among the student routers. Lab 2: Configuring EBGP Peerings Create two EBGP peerings, advertise networks into BGP, and redistribute your IGP into BGP. Additionally, you will notice the effects of BGP autosummarization and summarize your pod’s routes to your external neighbor. Lab 3: Configuring IBGP Peerings In this exercise, configure an IBGP peering with the other edge router in your pod, simulating a network with redundancy and giving a backup path in case there are problems with your other external path. Learn peering with loopback interfaces, the effect of BGP synchronization, and BGP next-hop behavior. Examine the effects of multihoming on path selection, both internally and on the external neighbors. Lab 4: Using AS-Path Filters and Regular Expressions Prevent your network from becoming a transit autonomous system by filtering updates to the external routers and manipulating path selection between the external peers using a combination of AS-path filters and regular expressions. Lab 5: Using Prefix Lists In this exercise, implement a policy about routes your AS accepts and advertises. Filter the routes advertised to your autonomous system by using prefix lists applied to routing updates from your external neighbors. Lab 6: Soft Reconfiguration and Route Refresh Explore less disruptive ways to make your BGP policy take effect other than clearing your peer relationships. Monitor and verify the actions of BGP Route Refresh and configure BGP soft inbound reconfiguration. Lab 7: Configuring the Weight Attribute Set a policy on individual routers using the Weight attribute in order to control BGP path selection on those routers. Configure a second BGP peering for each of your BGP routers, then set a weight value for routes received from each EBGP neighbor, and monitor the resulting path choice. Lab 8: Configuring the Local Preference Attribute Set a policy that affects your entire autonomous system using the Local Preference attribute to control BGP path selection by all routers with your autonomous system. Lab 9: AS-Path Prepending Use AS-Path Prepending to influence the BGP path chosen by other routers in the Internet for traffic bound for your AS. Configure AS-Path Prepending in order to make one path into your AS look more attractive than the other. Lab 10: Configuring the Multi-Exit Discriminator (MED) Attribute Use the MED attribute to influence the BGP path selection by routers in neighboring autonomous systems for traffic bound to your autonomous system. Lab 11: The Community Attribute Explore ways of using the Community attribute to tag routes. Configure the use of that attribute in setting local preference BGP policies within your autonomous system.
