Syntax: [no] bfd all-interfaces
While this command configures BFD for IS-IS on all of a router's IS-IS enabled interfaces, it is not
required that it be configured if you use the isis bfd command to configure specific interfaces. It
can be used independently or together with that command.
Enabling or disabling BFD for IS-IS for a specific interface
You can selectively enable or disable BFD on any IS-IS interface as shown in the following.
BigIron RX#(config-if-e1000-3/1)# isis bfd
