An engineer is designing a multicluster BGP network where each cluster has two route reflectors and four Route Reflector clients.
Which two options must be considered in this design?

A.	Clients must not peer with iBGP speakers outside the client cluster.
B.	Clients should peer with at least one other client outside of its own cluster.
C.	All route reflectors should be nonclient peers and the topology is partially meshed.
D.	All route reflectors must be nonclient peers in a fully meshed topology.
E.	Clients from all clusters should peer with all route reflectors.
