Configuration procedure
1. Configure basic MPLS L3VPN:
Configure OSPF on the MPLS backbone to allow the PEs and P device to learn the routes of the loopback
interfaces from each other.
Configure basic MPLS and MPLS LDP on the MPLS backbone to establish LDP LSPs.
Establish MP-IBGP peer relationship between the PEs to advertise VPN IPv4 routes.
Configure the VPN instance of VPN 1 on PE 2 to allow CE 2 to access the network.
Configure the VPN instance of VPN 1 on PE 1 to allow CE 1 to access the network.
Configure BGP between PE 1 and CE 1, and between PE 2 and CE 2 to inject routes of CEs into PEs.
After completing the configurations, execute the display ip routing-table command on CE 2,
you can see that CE 2 has learned the route to network 10.1.1.0/24, where the interface used
