With reference to the exhibit, which two statements are correct regarding the dual route reflectors in a cluster?

Choose two
  • A RR1 and RR2 must have the same duster ID to exchange routes learned from the client.
  • B RR1 and RR2 append the duster ID when advertising routes from dient to dient.
  • C RR1 and RR2 advertise routes learned from the clients to EBGP peers, using itself as the next hop.
  • D RR1 advertises routes from the client to RR2. using itself as the next hop.
Explanation

A route reflector adds its cluster ID to the CLUSTER_LIST when reflecting client-learned routes, including advertisements to other clients. For an eBGP advertisement, the advertising BGP speaker sets itself as the NEXT_HOP. In contrast, iBGP route reflection preserves the next hop, and redundant reflectors that must reflect routes to other clusters require different cluster IDs.
