Usage Guidelines

By default, PIM BFD is not enabled on an interface.

When using the pim bfd enable command, note the following points:

This command is applicable to NBMA interfaces and broadcast interfaces rather than P2P interfaces.
Before configuring this command, you must run the pim sm command on the interface to enable PIM-SM. You can run the undo pim sm command to disable PIM BFD on the interface.
PIM BFD depends on the BFD protocol. If the bfd command is not run to enable global BFD, the session status is BFD global disable though PIM BFD sessions can be set up.

The pim bfd enable command cannot work with the command that enables PIM over PPPoE.

Example
