As illustrated, after simultaneous failures between the route reflectors (RRs) and the clients, routes are not exchanged between Client1 and Client3 through the RRs.

Which statement is correct for this scenario?

Explanation

Route reflectors discard an incoming reflected route when their own cluster ID appears in the route’s CLUSTER_LIST. With the remaining connectivity, routes between Client1 and Client3 must pass from one route reflector to the other; therefore, the route reflectors require distinct cluster IDs so they do not reject each other’s reflected routes.
