1. Configure basic IPv6 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 VPN IPv6 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 the CEs into the
PEs.
For more information about basic MPLS L3VPN configurations, see "
L3VPNs."
2. Configure BGP AS number substitution:
# Configure BGP AS number substitution on PE 1, PE 2, and PE 3. For more information about
the configuration, see "
# Display routing information on CE 2. The output shows that CE 2 has learned the route
100::/96 from CE 1. A routing loop has occurred because CE1 and CE 2 reside in the same site.
