MPLS L3VPN configuration examples

This section provides examples on how to configure MPLS L3VPN.

Configuring MPLS L3VPNs using EBGP between PE and CE

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 attribute 1 1 1:1. VPN 2 uses route target attribute 222:2. Users of different VPNs
cannot access each other.
EBGP is used to exchange VPN routing information between CE and PE.
PEs use OSPF to communicate with each other and use MP-IBGP to exchange VPN routing information.
