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 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.
[PE2] bgp 100
[PE2-bgp] primary-path-detect bfd echo
# Configure FRR for VPN instance vpn1 to reference routing policy frr.
[PE2-bgp] ip vpn-instance vpn1
[PE2-bgp-vpn1] address-family ipv4 unicast
[PE2-bgp-ipv4-vpn1] fast-reroute route-policy frr
# Specify the preferred value as 200 for BGP routes received from CE 2. This value is greater than
the preferred value (0) for routes from PE 3, so PE 2 prefers the routes from CE 2.
[PE2-bgp-ipv4-vpn1] peer 10.1.1.1 preferred-value 200
[PE2-bgp-vpn1] quit
[PE2-bgp] quit
Verifying the configuration
# Display detailed information about the route to 4.4.4.4/32 on PE 2. The output shows the backup next
hop for the route.
