I have a 2801 with a PRI and 2 Fast Ethernet interfaces. We want to dual-home the gateway to separate core switches, with one Fast Ethernet interface to each switch.
My question is what is the best way to do this? I was thinking of putting both interfaces into a BVI interface, but is that ok to use for voice? Or would it be better to use a /30 on each interface, and then use the loopback IP as the routed IP?
The BVI works fine with voice. And the routed approach also. If you have a voice vlan to be connected directly to the router, the first solution is probably easier.
Hope this helps, please rate post if it does!
