Cisco Router Possible HSRP Issues - Out of Sync ??
Posted on 2007-07-26
I have two Cisco 2821 routers with HSRP configured.
On the primary, if I do a "sh standby" I get the same results on all of the interfaces - 1 state change, last state change 1w0d
If I do a "sh standby on the secondary box I get the last state change as 23:16, with each of the interfaces having a different number of state changes ranging from 13 to 45.
The two routers have different uptimes, so there's no surprise that the amount of state changes is only 1 on the primary. However, I have the following questions :
1. On the secondary box, wouldn't you expect the interfaces to have the same state change counts ?
2. Shouldn't the last state change time on the primary and the secondary router agree ?
3. Is it possible for HSRP to get out of sync and, if so, how and under what circumstances ?
Any help would be much appreciated.
