In the given network diagram, RR1 and RR2 are route reflectors within AS 65540. The role of a route reflector is to reduce the number of iBGP peering sessions required within an AS.
Each route reflector (RR1 and RR2) should have the same cluster ID to identify the route reflector cluster they belong to.
RR1 needs to be configured with BGP settings that include its role as a route reflector with appropriate cluster ID and neighbor configurations.
Examining the given options:
Option A: This configuration shows RR1 with a cluster ID, proper BGP setup, and correct neighbors within the AS 65540, which corresponds to the network diagram.
Router bgp 65540 bgp router-id 10.16.10.1 bgp cluster-id 10.16.10.1 neighbor 10.16.10.2 remote-as 65540 neighbor 10.16.10.2 route-reflector-client neighbor 10.16.10.5 remote-as 65540 neighbor 10.16.10.5 route-reflector-client neighbor 10.16.10.6 remote-as 65540 neighbor 10.16.10.6 route-reflector-client
Option B: This option does not match as closely to the network requirements as Option A.
Option C and Option D: Both these options are duplicates and appear similar to Option B, not providing the correct configuration for RR1 as per the network diagram.
Therefore, the correct answer is Option A.
