How's that for a subject line?
Ok I've narrowed down my problem to this. I have Cisco Catalyst 4006 core switch with the layer 3 router module. The router module has 2 gigabit ethernet ports that I have linked up to 2 Catalyst 2000 series switches.
The goal was to be able to use the same vlans across the entire network but the router module treats vlans on it's interfaces has it's own. So they are isolated and not exactly the same as the rest. I want to get them all the same so that vlan 103 on the router module is recognized by the other switches not on the router module.
The GBIC ports work like this. G1 and G2 are the ports that you see, controlled by the router module (L3). G3 and G4 are also controlled by the router module but are the routers connection to the switch backplane. Ports 2/1 and 2/2 are the actually switchports the router ports connect to.
Currently the gbics are all set to bridge and are in the same bridge-group.
What I need to know is what should I be looking at to accomplish my goal?
Do I need to enable bridging on the 2/1 and 2/2 ports? Do I need etherchannel?
I thought that by bridging it would act like this:
Switch -> bridgegroup -> switch and that all vlans would work.
