Chapter 35 Configuring IP Unicast Routing
Configuring BFD
To disable EIGRP BFD on all interfaces, enter the no bfd all-interfaces router configuration command.
To disable it on an interface, enter the no bfd interface interface-id router configuration command.
Configuring BFD for HSRP
HSRP supports BFD by default; it is globally enabled on all interfaces. If HSRP support has been
manually disabled, you can reenable it in interface or global configuration mode. All participating
devices must have HSRP enabled and CEF enabled (the default).
Beginning in privileged EXEC mode, follow these steps to reenable HSRP BFD:
To disable HSRP support for BFD on all interfaces, enter the no standby bfd all-interfaces global
configuration command. To disable it on an interface, enter the no standby bfd interface configuration
command.
Note If you disable standby BFD on an interface by entering the no standby bfd interface configuration
command, to activate BFD sessions on other interfaces, you must disable and reenable it globally by
entering the no standby bfd all-interfaces global configuration command followed by the standby bfd
all-interfaces global configuration command.
Step 5
end Return to privileged EXEC mode.
Step 6
show bfd neighbors [detail] Verify the configuration.
Step 7
copy running-config startup-config (Optional) Save your entries in the configuration file.

Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify an interface for a BFD session, and enter interface configuration
