Name
standby track — interface
Synopsis
standby [group] trackinterface[interface-priority] no standby [group] trackinterface[interface-priority]
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).
interface ethernet0 standby 1 ip 10.10.1.1 standby 1 preempt standby 1 track serial0 20
