bridge-group # priority

[Sam Oesterling]

I just wanted to ask a simple question to make sure I have this right.  I'm trying to create layer 2 redudancy to our CME router.  I thought it would be best to make sure all traffic egresses and ingreses from the same interface unless that interface or the switch it is connected to if offline.  Do I have the right confguration in mind to get this done?  I want to make sure nothing funky happens with STP.  Or would etherchannel be better?

If one of the routers will only be used in case of failover, I would configure HSRP on the routers for failover. If you're wanting to load balance, you'll need GLBP.

John,

I'm trying to create L2 redundancy between the router and the 3750 stack.  I will be also configuring HSRP for router redundancy, but I would rather the 3845 stay in operation if it is just a L2 failure.
