Tell me why this fails....

Here is something for anyone who has passed BCMSN to figure out.


Two switches, multiple vlans running HSRP. Each vlan configured with its own subnet and standby group 0.

configuration on each 3550 looks like the this

SW01:
vlan 10
ip add 172.16.1.2
standby ip 172.16.1.1
standby preempt
standby authentication xxx
standby priority 90

SW02:
vlan 10
ip add 172.16.1.3
standby ip 172.16.1.1
standby preempt
standby authentication xxx
standby priority 110

Both switches are in listen state. Again as stated all vlans in group 0, which there is roughly 15 of them. Without seeing a log can you figure out the problem?

not really enough info what trunk have you got between them?

basically what happened is that we had many many vlans in group 0 and there is a bug in IOS code and would have the active routers listed that were in a different vlans and then move to the listening state, rinse and repeat.
