Hello Pulkit,

use interface tracking for the wireless inteface

int fas0/0

standby 1 x.x.x.x

standby 1 pri 105

standby 1 track dot1q0.1

standby 1 preempt

standby 1 preempt is needed also on the other router in order to become active when the wireless fails.

Hope to help

HI Pulkit, [Pls RATE all Informative POST]

The standby track command allows you to specify another interface on the router for the HSRP process to monitor in order to alter the HSRP priority for a given group. If the line protocol of the specified interface goes down, the HSRP priority is reduced. This means that another HSRP router with higher priority can become the active router if that router has standby preempt enabled.

Pls RATE all Informative POST

Hello Pulkit,

active HSRP role is the result on an election on the LAN.

the track command allows to reduce by 10 the priority when the interface is down.

I used do1d0.1 just as placeholder here you need to specify the name of your wireless interface.

when that interface is down the priority is reduced from 105 to 95 the other router with defaul priority 100 will become the active router for the group.

When the tracked interface comes up again the active role changes again.

Hope to help
