Command Remarks
1. Enter system view.

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.

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.

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 policies."
