What action will a BGP route reflector take when it receives a prefix marked with the community
attribute NO ADVERTISE from a client peer?

A.
It will advertise the prefix to all other client peers and non-client peers.

B.
It will not advertise the prefix to EBGP peers.

C.
It will only advertise the prefix to all other IBGP peers.

D.
It will not advertise the prefix to any peers.

Explanation:
BGP requires that all BGP peers in the same autonomous system form an iBGP session with all
peers in the autonomous system. This is too difficult in many environments. Route reflectors are
fully functional iBGP speakers that form iBGP sessions with other iBGP speakers, and they also
perform a second function – they forward routes from other iBGP speakers to route reflector
clients. The route reflector clients and clients form a cluster.
