A.PE1 advertises spoke routes to CE1.

B.The primary VRF on PE1 is used to route data packets from the hub CE to the spoke sites.

C.The secondary VRF on PE1 contains routes learned from the spoke sites.

D.Spoke sites do not learn routes from other spoke sites directly.

A.ASBR2 swaps the BGP label and pushes an LDP transport label.

B.ASBR1 pops the LDP label, swaps the BGP label and forwards the IP packet to ASBR2.

C.PE1 pushes three labels on the IP packet: a VPN label, a BGP label, and an LDP transport label.

D.PE2 pops all labels and forwards the unlabeled packet to its destination.

A.Logical Partitioning of route reflectors works best when PEs are partitioned to support different VPRNs.

B.Logical Partitioning of route reflectors is simple and scalable, but requires more hardware.

C.Filtering at route reflectors requires either inbound filtering at the route reflector or outbound filtering at the PE routers.

D.Filtering at route reflectors allows the route reflector to filter routes received from PEs and only accept routes with a certain route distinguisher.
