IPv6 MPLS L3VPN configuration examples
Configuring IPv6 MPLS L3VPNs
Network requirements
CE 1 and CE 3 belong to VPN 1. CE 2 and CE 4 belong to VPN 2.
VPN 1 uses route target attributes 111:1. VPN 2 uses route target attributes 222:2. Users of different VPNs
cannot access each other.
Run EBGP between CE and PE switches to exchange VPN routing information.
PEs use OSPF to communicate with each other and use MP-IBGP to exchange VPN routing information.

Configuration procedure
1. Configure OSPF on the MPLS backbone to achieve IP connectivity among the PEs and the P switch:
# Configure PE 1.
