Question

Which two of the following statements concerning route reflectors are true?

Choose two

A Routes received from nonclient peers are reflected to route reflector clients as well as nonclient peers.
B Routes received from nonclient peers are reflected to route reflector cluster as well as OSPF peers.
C If a router received an iBGP route with the originator-ID attribute set to its own router ID, the route is discarded.
D Routes received from a route reflector client is reflected to other clients and nonclient peers.
E If a route reflector receives a route with a cluster-list attribute containing a different cluster ID, the route is discarded.

Explanation

A route reflector reflects routes learned from a client to all non-client peers and to its other client peers. A BGP router ignores a received route when its own BGP Identifier appears in the ORIGINATOR_ID attribute, preventing route-reflection loops.
