Configuring MPLS L3VPNs using iBGP 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 VPN target attribute 111:1. VPN 2 uses VPN target attribute 222:2. Users of different

VPNs cannot access each other.

iBGP 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.
