Configuring MPLS L3VPN FRR through IPv4 route backup
for a VPNv4 route
Network requirements
CE 1 and CE 2 belong to VPN 1.
Configure EBGP between CEs and PEs to exchange VPN routes.
Configure OSPF to ensure connectivity between PEs, and configure MP-IBGP to exchange VPNv4
routing information between PEs.
Configure MPLS L3VPN FRR on PE 2 to achieve the following purposes:
•
When the link PE 2—PE 3 operates correctly, traffic from CE 1 to CE 2 goes through the path
CE 1—PE 1—PE 2—PE 3—CE 2.
•
When BFD detects that the link between PE 2 and PE 3 fails, traffic from CE 1 to CE 2 goes
through the path CE 1—PE 1—PE 2—CE 2.
