BFD Probe

The BFD feature uses a Tracked Object Manager BFD probe session to detect communications failures with the neighbor. BFD probe sessions are able to detect communications failures with a neighbor in less than a second and are not protocol dependent. The probe configured on the interface can be the default routing protocol probe ($rte_default) or a named BFD probe. The default routing protocol probe already exists and does not have to be created. See Tracked Object Manager Configuration for a complete discussion of tracked object probes.

Use the probe bfd command, in global configuration mode, to create a named BFD probe and enter BFD probe configuration mode.

Once you have made any optional modification to the BFD session, place the probe inservice using the inservice command in BFD probe configuration mode.

This example enters configuration mode for a BFD probe named bfdProbe1:

System(su)->configure
System(su-config)->probe bfdProbe1 bfd
System(su-config-probe-bfd)->inservice
System(su-config-probe-bfd)->
