Verifying the configuration
# PE 2 does not advertise routes received from CE 1 to CE 2 because the same SoO attribute has
been configured for the CEs. Display the routing table of CE 2. The output shows that the route
100.1.1.1/32 has been removed.

Configuring MPLS L3VPN FRR through VPNv4 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 1 to achieve the following purposes:
•
When the link PE 1—PE 2 operates correctly, traffic from CE 1 to CE 2 goes through the path
CE 1—PE 1—PE 2—CE 2.
