This is a self-study technical course that provides students with in-depth knowledge of BGP, the routing protocol that is one of the underlying foundations of the Internet and new-world technologies such as Multiprotocol Label Switching (MPLS). It prepares students to design and implement efficient, optimal, and trouble-free BGP networks.

  • Examine the effects of BGP auto-summarization
  • Summarize routes to your neighbour
  • Implement BGP TTL Security
  • Implement BGP Authentication
Lab 2: Configuring IBGP Peerings
  • Configure an IBGP peering with another edge router
  • Peering with loopback interfaces
  • Examine effect of BGP synchronization
  • Discover BGP next-hop behaviour

Lab 4: Using Prefix Lists
  • Filter advertised AS routes using prefix lists
  • Implement Outbound Route Filtering
Lab 5: Configure Route Maps for BGP Filtering
  • Configure a route map as a BGP filter
Lab 6: Configuring the Weight Attribute
  • Configure a second BGP peering for each router
  • Set a weight value for routes received from each EBGP neighbour
  • Monitor the resulting path choice
Lab 7: Configuring the Local Preference Attribute
  • Use the Local Preference attribute to control BGP path selection
  • Lab 8: AS-Path Prepending
    • Configure AS-Path Prepending to make one path into your AS look more attractive than the other
    Lab 9: Configuring the Multi-Exit Discriminator (MED) Attribute
    • Use the MED attribute to influence the BGP path selection by routers in neighbouring systems
    Lab 10: Using the Community Attribute
    • Configure the community attribute in setting local preference BGP policies
    • Lab 11: Using Route Reflectors
    • Configure a hierarchical route reflector structure
    • Examine the effects of route reflectors on routing updates
    Lab 12: Monitoring and Tuning BGP Resource Use
    • Examine the effects of BGP session establishment and route updates on router resources
