© 2006 Cisco Systems, Inc. All rights reserved. MPLS v Module Summary The VRF table is a virtual routing and forwarding instance separating sites with the same connectivity requirements. Configuring VRF tables requires defining the VRF name, RD, and import and export RTs. MP-BGP configuration must define the neighbors, define the address family, for VPNv4 routing, and finally activate the neighbors. RIPv2 and EIGRP routing for PE to CE requires use of the address-family ipv4 command to define the routing context. Redistribution is also required between IGP and BGP.

© 2006 Cisco Systems, Inc. All rights reserved. MPLS v Module Summary (Cont.) Monitoring MPLS VPN operations includes monitoring MP-BGP neighbor status, VRF routing process, and CEF and LFIB status. The MPLS VPN routing model implements MP-BGP as the superbackbone for OSPF. PE-to-CE OSPF routing is defined as a new routing process via the VRF name. The MPLS VPN routing model implements BGP routing between PE and CE as BGP instances using the command address-family ipv4. MPLS VPN troubleshooting uses a systematic process starting at the ingress PE router and moving to the egress PE router using a variety of show commands.
