I will be installing a layer 3 switch to breakup one large broadcast domain. I will be creating trunks from each data closet access switch, to the new layer 3 switch. This will be a collapsed core setup. My question is, I have 10 closets to move over, if I do one at a time, with the new vlans being on their own subnet, I know that inter-vlan routing can be used to talk to other vlans ending on that switch, but how will it allow traffic to talk to the rest of the flat network. Would I create a routed interface on the switch using the no switchport command, and then assign it an ip/secondary address that falls within the ip range being used. 192.168.x.x with a b mask. Also, in this scenario, will broadcasts be forwarded. I am looking for the new dist/core switch to be an endpoing for all traffic, and then static route to either the firewall or remote sites from there. Any insight would be greatly appreciated.
