, CE 1 and CE 2 belong to VPN 1, and are connected to PE 1 and PE 2. The
two CEs have the same AS number, 600. Configure BGP AS number substitution on the PEs to
avoid route loss.

Configuration procedure
1.
Configuring 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.
