(Optional) Binding IP FRR and BFD

Binding IP FRR and BFD enables the lower layer to fast respond to a link change so that traffic can be rapidly switched to the backup link if the primary link fails.

Context

After the parameter frr-binding is set to bind the BFD status to the link status of an interface, link failures can be detected rapidly. This ensures that traffic is rapidly switched to the backup link if the primary link fails.

Perform the following steps on the router where IP FRR and BFD need to be bound:

Procedure

Bind IP FRR and BFD in an OSPF process.
1. Run system-view
  The system view is displayed.
2. Run ospf
  An OSPF process is started, and the OSPF view is displayed.
3. Run bfd all-interfaces frr-binding
  IP FRR and BFD are bound in the OSPF process.
4. Run commit
  The configuration is committed.
Bind IP FRR and BFD on a specified OSPF interface.
1. Run system-view
  The system view is displayed.
2. Run interface interface-type interface-number
  The interface view is displayed.
3. Run ospf bfd frr-binding
  IP FRR and BFD are bound on the interface.
  
  The BFD configuration on an interface takes precedence over that in an OSPF process.
4. Run commit
  The configuration is committed.
