Configuring IP Unicast Routing
Configuring BFD
DETAILED STEPS
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.
BEFORE YOU BEGIN
Configure BFD parameters on the interface as described in the Configuring BFD Session Parameters on an Interface,
page 886.
Ensure that all participating devices have HSRP enabled and CEF enabled (the default).
Command Purpose
1. configure terminal Enter global configuration mode.
2. router eigrp as-number Specify an EIGRP autonomous system number, and enter router
configuration mode.
3. log-adjacency changes [detail] Configure the switch to send a system logging message when an
EIGRP neighbor goes up or down.
4. bfd {all-interfaces | interface
interface-id}
Enable BFD for EIGRP.
Enter all-interfaces to globally enable BFD on all interfaces
associated with the EIGRP routing process.
Enter interface interface-id to enable BFD on a per-interface
basis for one or more interfaces associated with the EIGRP
routing process.
5. end Return to privileged EXEC mode.
6. show bfd neighbors [detail] Verify the configuration.
7. copy running-config
startup-config
(Optional) Save your entries in the configuration file.
