Usage Guidelines

Usage Scenario

In static BFD, BFD session parameters are set manually and BFD session establishment requests are delivered manually. Then static BFD can quickly detect faults on links. You can run the isis bfd static command to enable static BFD on a specified interface to establish static BFD sessions on specified links.

Prerequisites

IS-IS has been enabled on the interface using the isis enable command.

Precautions

If the isis bfd block, isis bfd enable, and isis bfd static commands are run, only the last command takes effect.
