Configuration procedure
1. Configure IP addresses for interfaces, and configure BGP and MPLS L3VPN:
For information about how to configure MPLS L3VPN, see "错误！未找到引用源。."
2. Configure MPLS L3VPN FRR:
# On PE 1, create a routing policy named vpnfrr to specify the backup nexthop as 3.3.3.3.
<PE1> system-view
[PE1] route-policy vpnfrr permit node 10
[PE1-route-policy] apply fast-reroute backup-nexthop 3.3.3.3
[PE1-route-policy] quit
# On PE 1, configure a routing policy named backup to set the route cost to 10.
[PE1] route-policy backup permit node 10
[PE1-route-policy] apply cost 10
[PE1-route-policy] quit
