HSRP Failing with Vlan and Physical interface

[DEENA SLOAN]

We have Router1 and Router 2  interface's that are trunked to a switch and Vlan/Vlans that flow through the interface that is trunked.

When the physical interface on Router 1 fails it goes to standby but the vlan interface is staying active on router 1. The physical

interface on Router 2 becomes active, but the Vlan interface on Router 2 stays in standby. This causes the Vlan to become confused

in which way the data should flow. The only way to fix it is to physically shutdown the Vlan interface on Router 1 for Router 2 to become active.

We have tried the track interface command on the Vlan interface but it does not work. Any suggestions?

Here are the config for the physical interface and the Vlan interface.

Thanks Deena

Router 1

Physical interface:

interface GigabitEthernet2/4
description ***PRI S1110 A/L***
switchport trunk encapsulation dot1q
switchport trunk native vlan 1000

standby 11 track GigabitEthernet2/4

Router 2

Physical interface:

You have an issue there with your priority. You have standby 11 priority 115 on Router 1 while tracking interface G2/4. If you do not set an explicit decrement value, then the value is       decreased by 10 for each interface that goes down, and decrements are       cumulative. Since Router 2 is left at default (100) it cannot become active because it will always have a lower priority. You may want to set your priority on router 1 to something lower than 110, like 105.
