300-320 Question #390: Real Exam Question with Answer & Explanation

The correct answer is C: All RRs must be non client peers in a fully meshed topology. 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 t

Question

An engineer is designing a multi cluster bgp network, each cluster has 2 RRs and 4 RR clients, which 2 options must be considered?

Options

AClients from all clusters should peer with all RRs
BAll route reflectors should be non client peers & topology partially meshed
CAll RRs must be non client peers in a fully meshed topology
DClients must not peer with IBGP speakers outside the client router
EClients should peer with at least one other client outside it's cluster

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.
