Binding IP FRR and BFD
Binding IP FRR and BFD
Context
During the configuration of OSPF
IP FRR, the lower layer needs to fast respond to the link change so
that traffic can be rapidly switched to the backup link in the case
of a link failure. Bind BFD to the link status so that link faults
can be detected rapidly. This ensures that traffic is rapidly switched
to the backup link in the case of link failures.
Binding OSPF
IP FRR and BFD can configure in a specified process or on a specified
interface. The priority of BFD configured on an interface is higher
than that of BFD configured in an OSPF process. If BFD is enabled
on an interface, a BFD session is established according to the BFD
parameters set on the interface.
Procedure
Bind IP FRR and BFD in an OSPF process.
Run system-view
The system view is displayed.
Run ospf [ process-id | router-idrouter-id | vpn-instancevpn-instance-name ] *
The
OSPF process is enabled, and the OSPF view is displayed.
Run bfd all-interfacesfrr-binding
IP FRR
and BFD are bound in the OSPF process.
Bind IP FRR and BFD on a specified OSPF interface.
