MPLS L3VPN configuration examples
Configuring basic MPLS L3VPN
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.
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.
