3750 as a port channel bridge

I have 3750 core/distribution switches with routing enabled in two offices connected with copper link and L3 port channel interfaces. NewOffice#2 has moved about 5 miles farther away from office#1 and I have to deploy new core/distribution switch connect it to old core#2 via F.O and move all access switches with it. Old core will stay in old #2 offices as a bridge between office#1 and new office#2

Office#1core<->copper (Ethernet) <->oldoffice#2core<->f.o. <->new office#2core

How I should configure port channels ports on oldoffice#2 core to act as bridge between office#1 core/dist and newoffice#2 core/dist without changing anything else (ip, etc) on whole network

Thank you

Re: 3750 as a port channel bridge

So you must connect two 3750 with 5 miles optical fiber? If yes you must to use gbic LX/LH for long distance.
