convergence. When the OSPF neighbor relationship goes Down, the BFD session between OSPF
neighbors is dynamically deleted.
Before configuring BFD for OSPF, enable BFD globally.
Perform the following steps on the router:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bfd
BFD is globally configured.
Step 3 Run:
quit
Return to the system view.
Step 4 Run:
interface interface-type interface-number
The interface view is displayed.
Step 5 Run:
ospf bfd enable
BFD for OSPF is configured. The default parameter values are used to create a BFD session.
If all the interfaces in a certain process are configured with BFD and their neighbor relationships
are in the Full state, OSPF creates BFD sessions with default parameter values on specified
interfaces in the process.
Step 6 (Optional) Run:
ospf bfd { min-rx-interval receive-interval | min-tx-interval transmit-interval |
detect-multiplier multiplier-value | frr-binding
BFD session parameters are modified.
You can skip this step. The default interval at which BFD packets are transmitted and the default
detection multiplier are recommended.
The parameters are configured based on the network status and network reliability requirements.
A short interval at which BFD packets are transmitted can be configured for a link that has a
higher requirement for reliability. A long interval at which BFD packets are transmitted can be
configured for a link that has a lower requirement for reliability.

NOTE
The priority of BFD for OSPF configured on an interface is higher than that of BFD for OSPF configured
for a process.
