Step Command Remarks
5. Create a routing policy
and enter routing policy
view.
route-policy route-policy-name permit
node node-number
By default, no routing policy is
created.
This step is required to enable MPLS
L3VPN FRR in Method 2.
For more information about this
command, see Layer 3—IP Routing
Command Reference.
6. Set the backup next hop
for FRR.
apply fast-reroute backup-nexthop
ip-address
By default, no backup next hop
address is set for FRR.
This step is required to enable MPLS
L3VPN FRR in Method 2.
For more information about this
command, see Layer 3—IP Routing
Command Reference.
7. Return to system view. quit N/A
8. Enter BGP view. bgp as-number N/A
9. (Optional.) Use
echo-mode BFD to detect
the connectivity to the next
hop of the primary route.
primary-path-detect bfd echo
By default, ARP is used to detect the
connectivity to the next hop.
Use this command if necessary in
VPNv4 route backup for an IPv4
route.
For more information about this
command, see Layer 3—IP Routing
Command Reference.
10. Enter BGP-VPN instance
view.
ip vpn-instance vpn-instance-name N/A
11. Enter BGP-VPN IPv4
unicast address family
view.
address-family ipv4 [ unicast ] N/A
12. Enable MPLS L3VPN FRR.
• (Method 1) Enable MPLS L3VPN
FRR for the address family:
pic
• (Method 2) Reference a routing
policy to specify a backup next
hop for the address family:
fast-reroute route-policy
route-policy-name
By default, MPLS L3VPN FRR is
disabled.
Method 1 might result in routing
loops. Use it with caution.
By default, no routing policy is
referenced.
The apply fast-reroute
backup-nexthop command can take
effect in the referenced routing
policy. Other apply commands do
not take effect.
