An engineer is designing a multi cluster bgp network, each cluster has 2 RRs and 4 RR clients, which 2 options must be considered?
A . Clients from all clusters should peer with all RRs
B . All route reflectors should be non client peers & topology partially meshed
C . All RRs must be non client peers in a fully meshed topology
D . Clients must not peer with IBGP speakers outside the client router
E . Clients should peer with at least one other client outside it’s cluster

Answer: CD

Explanation:

Route reflectors must still be fully IBGP meshed with nonclients. Therefore, route reflectors reduce meshing within clusters, but all mesh links outside the cluster must be maintained on the route reflector. The route reflector clients get information from IBGP speakers outside the cluster via the route reflector.
