A.The virtual routing and forwarding table is separate from the global routing table that exists on PE routers. Routes are injected into the VRF from the CE-PE routing protocols for that VRF and any MP-BGP announcements that match the defined VRF RTs
B.Multiprotocol Border Gateway Protocol is run between PE and CE routers to exchange customer prefixes in a VPNv4 format
C.A customer edge router peers at Layer 3 to the provider edge. The PE-CE interface runs either a dynamic routing protocol (eBGP, RIPv2, EIGRP, OSPF) or a static routing protocol (Static, Connected)
D.VPNv4 address is the combination of the RT and customer IPv4 prefix. These VPNv4 prefixes are passed in MP-BGP
