Configuration procedure
1. Configure IP addresses for interfaces, BGP, and MPLS L3VPN:
For information about how to configure MPLS L3VPN, see "Configuring MPLS L3VPNs using EBGP
between a PE and a
CE."
2. Configure MPLS L3VPN FRR:
# On PE 2, create a routing policy named vpnfrr to specify the backup next hop as 3.3.3.3.
<PE2> system-view
[PE2] bfd echo-source-ip 54.54.54.54
[PE2] route-policy vpnfrr permit node 10
[PE2-route-policy] apply fast-reroute backup-nexthop 3.3.3.3
# On PE 2, enable FRR in VPN 1 and reference the routing policy vpnfrr.
[PE2] ip vpn-instance vpn1
[PE2-vpn-instance-vpn1] fast-reroute route-policy vpnfrr
[PE2-vpn-instance-vpn1] quit
3. Verify the configuration:
Display routes destined for 4.4.4.4/32 on PE 2. You can see that the active route has a backup
next hop.
[PE2] display ip routing-table vpn-instance vpn1 4.4.4.4 verbose
