511BConfiguration procedure
1. Configure IP addresses and masks for interfaces as shown in 819HTable 24, and configure BGP and
MPLS L3VPN. (Details not shown.)
For more information about configuring basic MPLS L3VPN, see "
820HConfiguring basic MPLS
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
[PE1-bgp-default-vpn1] address-family ipv4 unicast
[PE1-bgp-default-ipv4-vpn1] fast-reroute route-policy frr
[PE1-bgp-default-ipv4-vpn1] quit
[PE1-bgp-default-vpn1] quit
# Specify the preferred value as 100 for BGP VPNv4 routes received from PE 2. This value is
greater than the preferred value (0) for routes from PE 3, so PE 1 prefers the routes from PE 2.
[PE1-bgp-default] address-family vpnv4
[PE1-bgp-default-vpnv4] peer 2.2.2.2 preferred-value 100
[PE1-bgp-default-vpnv4] quit
[PE1-bgp-default] quit
3. Enable MPLS BFD on PE 2.
<PE2> system-view
[PE2] mpls bfd enable
512BVerifying the configuration
# Display detailed information about the route to 4.4.4.4/32 on PE 1. The output shows the backup
next hop for the route.
[PE1] display ip routing-table vpn-instance vpn1 4.4.4.4 32 verbose
