Configuration procedure
1. Configure IP addresses and masks for interfaces as shown in
MPLS L3VPN. (Details not shown.)
For more information about configuring basic MPLS L3VPN, see
L3VPN."
2. Configure MPLS L3VPN FRR on PE 1:
# Configure BFD to test the connectivity of the LSP to 2.2.2.2/32.
<PE1> system-view
[PE1] mpls bfd enable
[PE1] mpls bfd 2.2.2.2 32
# Create routing policy frr, and specify the backup next hop as 3.3.3.3 for the route to
4.4.4.4/32.
[PE1] ip prefix-list abc index 10 permit 4.4.4.4 32
[PE1] route-policy frr permit node 10
[PE1-route-policy] if-match ip address prefix-list abc
[PE1-route-policy] apply fast-reroute backup-nexthop 3.3.3.3
[PE1-route-policy] quit
# Configure FRR for VPN instance vpn1 to use routing policy frr.
[PE1] bgp 100
[PE1-bgp-default] ip vpn-instance vpn1
