How to Configure Bidirectional Forwarding Detection
Purpose
Enables privileged EXEC mode.
• Enter your password if prompted.
Enters global configuration mode.
Enters interface configuration mode.
Enables or disables BFD on a per-interface basis for one or
more interfaces associated with the OSPF routing process.
You should use the disable keyword only if you
Note
enabled BFD on all of the interfaces that OSPF is
associated with using the bfd all-interfaces
command in switch configuration mode.
Exits interface configuration mode and returns the switch to
privileged EXEC mode.
(Optional) Displays information that can help verify if the
BFD neighbor is active and displays the routing protocols
that BFD has registered.
Note If hardware-offloaded BFD sessions are configured
with Tx and Rx intervals that are not multiples of
50 ms, the hardware intervals are changed.
However, output from the show bfd neighbors
details command displays the configured intervals,
not the changed ones.
(Optional) Displays information that can help verify if BFD
support for OSPF has been enabled.
