Configures
Hot Standby Routing Protocol (HSRP)
Default
Group, 0; interface priority, 10
Description
This command configures the HSRP interface to track another
interface
. If the other interface goes
down, the HSRP interface’s standby priority decreases by the
value interface-priority
. The rationale
for this behavior is that if the tracked interface is down, this
router is less desirable as a standby router. The
standby
track
command must be
used in combination with the preempt
command.
Example
In this example, ethernet0
is the HSRP interface
tracking interface serial0
. If
serial0
goes down,
ethernet0
’s priority is decreased by 20.
When serial0
comes back up,
ethernet0
’s priority is increased by 20
(i.e., returned to its original value).
