Section 4: EGP Protocols (17 Points)
Configure BGP, as shown in Figure 1-14, with the following peering: R3–R2, R8–R2, R6–R2, R6–R8, R7–R8, R6–R5. Ensure the most suitable interfaces are used to maintain resilience for BGP peering (except for R2 and R3, use 172.16.0.0/16 addresses for all peering to and from these routers).
Ensure minimal configuration on R8.
Inject the following networks into BGP via new loopback interfaces:
R3: 20.200.200.1/24 and 20.20.20.1/24 R5: 20.20.20.1/24 and 200.20.20.1/24 R7: 30.30.30.30/29
Ensure that R6 BGP routing table prefers to use AS1000 for network 20.20.20.0/24; do not use BGP weight, BGP local preference, MED, neighbor metric related statements, metric manipulation, summarization, or pre-pending to achieve this. Perform configuration on R6 only.
All BGP speakers are to be able to communicate with all advertised BGP networks.
