Subject: Re: HSRP/Spanning Tree issue??? [7:19639]
You are correct that, not only should it work, but you don't need
Spanning
Tree unless you have more than one connection between the two
switches.
As an aside, make sure you are trunking on the link between the two
switches......
- From what you're described, I don't see why this wouldn't
work.........
Can you e-mail me a copy of your configs (from the two 7200s and
3548s).
Perhaps that might help.....
