HI Iqbal.
Check your IOS on the router. Make sure that it supports HSRP. Usually when a router/swich gives you the error you are experiencing its becuase the command is not supported.
Good luck.

Jerald,

I agree with your best practice of using priorities ending in “5″. Allow me to clarify why the example given still works regardless.

Should the s0/0 go down off Router1 the priority would drop to 100. This is EQUAL to Router2 (priority 100 as well). Why then does Router2 take over? Router2 has a higher IP address; the tie breaker when priorities are equal. So Router2 192.168.0.3 wins over Router1 192.168.0.2 given both priorities are now 100. Sure this works but I prefer a definitive use of the priority command for Router 1: standby 1 priority 105

Brent, You can issue the “show stand brief” command to show the status of all HSRP groups.

Also, best practice is to use priorities that are only 5 numbers apart. For example I would use a priority of 110 on router 1 and a priority of 105 on router 2. The reason is that by default the priority decreases by 10 so router 1′s priority would now be 100 which is lower than router 2′s priority of 105. In the example above both if s0/0 went down then router 1′s priority would decrease by 10 to 100 which would be the same as router 2. You can however change the default amount that the priority is lowered by.

I have to connect two locations from my location with two ISP’z links (Total 4 links,ISP-1 Primary,Secondary same way ISP-2 Primary,Secondary).

How do I configure HSRP with this for two locations?
Can some one help me on this?

Does anyone know the command to show all HSRP groups that are currently active? I am currently running the show standby vlan xxx but would rather be able to view all active in one shot.

Thanks
