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.
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.
