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 1 to allow CE 1 to access the network.
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 3 to allow CE 3 to access the network.
Configure BGP as the PE-CE routing protocol, and redistribute routes of CEs into PEs.
For more information about basic MPLS L3VPN configurations, see
L3VPN."
2. Configure BGP AS number substitution:
