Configuration procedure
1. Configure IP addresses and masks for interfaces as shown in Table 23 , and configure BGP and
MPLS L3VPN. (Details not shown.)
For more information about configuring basic MPLS L3VPN, see "
Configuring basic MPLS
L3VPN ."
2. Configure MPLS L3VPN FRR on PE 2:
# Configure the source IP address of BFD echo packets as 12.1.1.1.
<PE2> system-view
[PE2] bfd echo-source-ip 12.1.1.1
# Create routing policy frr, and specify the backup next hop as 3.3.3.3 for the route to
4.4.4.4/32.
[PE2] ip prefix-list abc index 10 permit 4.4.4.4 32
[PE2] route-policy frr permit node 10
[PE2-route-policy] if-match ip address prefix-list abc
[PE2-route-policy] apply fast-reroute backup-nexthop 3.3.3.3
[PE2-route-policy] quit
# Use echo-mode BFD to detect the primary route connectivity.
