MPLS L3VPN configuration examples
Configuring MPLS L3VPNs using EBGP between a PE and a 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 111:1. VPN 2 uses route target attribute 222:2. Users of different VPNs
cannot access each other.
A PE and its connected CE use EBGP exchange VPN routing information.
PEs use OSPF to communicate with each other and use MP-IBGP to exchange VPN routing information.
