Configuring MPLS L3VPN FRR
There are two methods to configure MPLS L3VPN FRR:
• Method 1—Execute the pic command in BGP-VPN IPv4 unicast address family view. The device
calculates a backup next hop for a BGP route in the VPN instance if there are two or more
unequal-cost routes to reach the destination.
• Method 2—Execute the fast-reroute route-policy command in BGP-VPN IPv4 unicast address family
view to reference a routing policy in which a backup next hop is specified by using the command
apply [ ipv6 ] fast-reroute backup-nexthop. The backup next hop calculated by the device must be
the same as the specified backup next hop. Otherwise, the device does not generate a backup next
hop for the primary route. You can also configure if-match clauses in the routing policy to identify
the routes protected by FRR.
If both methods are configured, Method 2 takes precedence over Method 1.

2. Enable MPLS BFD.
mpls bfd enable
The mpls bfd enable command
applies to VPNv4 route backup for a
VPNv4 route and IPv4 route backup
for a VPNv4 route. For more
information about this command,
see MPLS Command Reference.
The bfd echo-source-ip command is
required when echo-mode BFD is
used to detect primary route
connectivity in VPNv4 route backup
for an IPv4 route. For more
information about this command,
see High Availability Command
Reference.
3. Configure the source IP
address for BFD echo
packets.
