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 VPN target attributes 111:1. VPN 2 uses VPN target attributes 222:2. Users of different
VPNs cannot access each other.
• EBGP is used to exchange VPN routing information between CEs and PEs.
• 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 router.
# Configure PE 1.
