Step Command Remarks
1. Enter system view. system-view N/A
2. Configure the source address
of echo packets.
bfd echo-source-ip ip-address
By default, no source address is
specified for echo packets.
This step is required when echo-mode
BFD is used to detect the connectivity to
the next hop of the primary route.
Specify a source IP address that does
not belong to any local network.
For more information about this
command, see High Availability
Command Reference.
3. 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 when Method 2 is
used to enable BGP FRR.
For more information about this
command, see Layer 3—IP Routing
Command Reference.
4. Set the backup next hop for
FRR. apply fast-reroute
backup-nexthop ip-address
By default, no backup next hop is set.
This step is required when Method 2 is
used to enable BGP FRR.
For more information about this
command, see Layer 3—IP Routing
Command Reference.
5. Return to system view. quit N/A
6. Enter BGP view. bgp as-number N/A
7. (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.
8. (Optional.) Enter BGP-VPN
instance view.
ip vpn-instance
vpn-instance-name
N/A
9. Enter BGP IPv4 unicast
address family view or
BGP-VPN IPv4 unicast
address family view.
address-family ipv4 [ unicast ] N/A
10. Enable BGP FRR.
• (Method 1) Enable BGP
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, BGP 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 and apply ipv6
fast-reroute backup-nexthop
commands can take effect in the
referenced routing policy. Other apply
commands do not take effect.
