Configuration procedure
Configuring OSPF FRR to calculate a backup next hop using the LFA algorithm
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, the source address of
echo packets is not configured.
3. Enter interface view.
interface
interface-type
interface-number
N/A
4. Enable LFA calculation on an
interface.
ospf fast-reroute lfa-backup
By default, the interface on which LFA
calculation is enabled can be selected
as a backup interface.
5. Return to system view.

N/A
6. Enter OSPF view.

7. Enable OSPF FRR to
calculate a backup next hop
by using the LFA algorithm.
fast-reroute lfa
[
abr-only
]
By default, OSPF FRR is not
configured.
If
abr-only
is specified, the route to
the ABR is selected as the backup
path.
Configuring OSPF FRR to specify a backup next hop using a routing policy
Before you configure this task, use the apply fast-reroute backup-interface command to specify a
backup next hop in the routing policy to be referenced. For more information about the apply
fast-reroute backup-interface command and routing policy configuration, see "Configuring routing
polici
es."
To configure OSPF FRR to specify a backup next hop using a routing policy:
Step Command Remarks
1. Enter system view.

N/A
2. Configure the source
address of echo packets.
bfd echo-source-ip
ip-address
By default, the source address of
echo packets is not configured.
3. Enter OSPF view.
ospf

4. Enable OSPF FRR to specify
a backup next hop by using a
routing policy.
fast-reroute route-policy
route-policy-name
By default, OSPF FRR is not
configured.
Configuring BFD for OSPF FRR
By default, OSPF FRR does not use BFD to detect primary link failures. To speed up OSPF
convergence, enable BFD single-hop echo detection for OSPF FRR to detect primary link failures.
To configure BFD for OSPF FRR:
