Configuring BFD on HSRP

You can configure BFD for the Hot Standby Router Protocol (HSRP). The active and standby HSRP
routers track each other through BFD. If BFD on the standby HSRP router detects that the active HSRP
router is down, the standby HSRP router treats this event as an active time rexpiry and takes over as the
active HSRP router.
The show hsrp detail will show this event as BFD@Act-down or BFD@Sby-down.
BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command).
Enable the BFD feature. See the
Configure the BFD session parameters. See the
page 5-8
Enable the HSRP feature. See the Cisco Nexus 7000 Series NX-OS Unicast Routing Configuration
Guide, Release 5.x, for more information.
