Example 1 for configuring MPLS L3VPN FRR
Network requirements
CE 1 and CE 2 belong to VPN 1. The route target used by VPN 1 is 111:1.
Configure EBGP between the CEs and PEs to exchange VPN route information.
Between the PEs, configure OSPF to enable them to communicate, and configure MP-IBGP to exchange
VPN route information.
Configure FRR on PE 1 so that when the link between PE 1 and PE 2 fails, traffic from CE 1 to CE 2 can
be switched to the link from PE 1 to PE 3.
