Configuring Mpls L3Vpn Frr Through Vpnv4 Route Backup For A Vpnv4 Route - HP 6127xlg Configuration Manual

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.
When BFD detects that the LSP between PE 1 and PE 2 fails, traffic from CE 1 to CE 2 goes through
•
the path CE 1—PE 1—PE 3—CE 2.
