I easily get confused myself with this but, remember unless you disable ip
routing and do not have an ip on the interface. IOS routes first then
bridges. CRB and IRB is there in case we do not have ip on our interface
but, still want to route ip traffic coming from the bridge. I hope I am
making sense. Of course most times when I answer these posts I wind up
looking like a fool!
With DLSW+ we are taking bridged SNA to the local TCP peer.

Subject: Short Question about DLSW, CRB & IRB
I had a thought nagging in the back of my mind every time I type 'dlsw
bridge-group 1' on interface that already has a IP network on it.
Isn't this a form of Concurrent Routing and Bridging? I'm surprised that we
don't have to setup CRB first.
Follow up question,
Is there a likely scenario where you have to do dlsw bridging and/or CRB,
IRB?
Or do these different bridging modes break each other?
