A.They are used by VPRNs to control the distribution of VPN routing information.

B.They are used to identify the VRF table for a prefix at the receiving PE.

C.They are distributed to all PEs and CEs that are part of the VPRN.

D.They are distributed to PEs to identify the VRF table that a VPN-IPv4 prefix is associated with.

A.The number of VPRN routes can become very large. MP-BGP can support a very large number of routes.

B.MP-BGP can carry routing information for a number of different address families.

C.MP-BGP is designed to exchange information between routers that are not directly connected. This feature keeps VPRN routing information out of P-routers.

D.All of the above statements are valid reasons for using MP-BGP as a VPRN routing protocol.

E.MP-BGP can carry additional information attached to a route as an optional BGP attribute.

A.Router R1 is the LSP head-end and can be a PLR.

B.All routers along the path, R1, R2, and R3 can be PLRs.

C.If the R1-R2 link fails, router R4 becomes an MP.

D.If the R2-R3 link fails, router R3 becomes a PLR.

A.Independent control mode; downstream unsolicited.

B.Ordered control mode; downstream unsolicited.

C.Ordered control mode; downstream on demand.

D.Independent control mode; downstream on demand.
