MPLS L3VPN configuration examples
Configuring MPLS L3VPNs using EBGP between PE and CE
Network requirements
• CE 1 and CE 3 belong to VPN 1, while CE 2 and CE 4 belong to VPN 2.
• VPN 1 uses VPN target attributes 111:1, while 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 CE and PE.
• PEs use OSPF to communicate with each other and use MP-IBGP to exchange VPN routing
information.
