Configuration procedure
1. Configuring 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 an MP-IBGP peer relationship between the PEs to advertise VPNv4 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 as the PE-CE routing protocol, and redistribute routes of the CEs into the

PEs.
For more information about basic MPLS L3VPN configurations, see
L3VPN."
# Execute the display ip routing-table command on CE 2. The output shows that CE 2 has
learned the route to network 10.1.1.0/24, where the interface used by CE 1 to access PE 1
resides. However, it has not learned the route to the VPN (100.1.1.0/24) behind CE 1.
