Before I ask my question I want to explain our unique infrastructure. We have two buildings across the street from eachother. Building A has a T1 line serving about 40 computers. Building B has two cable internet lines. Both buildings are linked together with two Cisco Aironet 1300 Series ap's acting as a wireless bridge.
We want our cable lines to remain separate and not shared among certain departments.
My question is: How can I set-up our network in such a way so that the T1 and the cable lines backup eachother?
In the future I would like to load balance as bandwidth is becoming an issue for us. But for right now I would be happy with just backing up the connections.
