A.VPN PE PE, the VPN route is exchanged between the ingress and the egress.

B.ASBR VPNV4, VPNv4 does not save routes, and does not advertise between routes.

C.Reporting Forwarding Layer Labels Up to two are required in the script.

D.Cross-domain mode is not suitable when using multiple VPN-Option-c ASs.

A.BSR C-RP C-RP collects information from received packets.

B.PIM-SM C-BSR There may be multiple BSR domains, but only one election.

C.BSR Bootstrap PIM-SM BSR C-RP floods the message to advertise information and information to all
routers in the domain.

D.A C-BSR C-RP C-RP packet can also be received to collect information.

C.SSM uses Shortest-Path Trees Only

D.SSM uses shared Trees only

E.SSM is best suited for applications that are of one-to-many category

F.The use of SSM is recommended when there are many sources and it is desirable to keep the amount of mroute state in the routers in the network to a minimum.
