New to Cisco so excuse my product ignorance. I'd like to design a network with 3*3750 as the Core/Distribution layer and a number of 2960 as the access layer.

I'm thinking of trunking the 3750s to create one virtual router. I'd like to use 2 uplink ports on each 2960 to connect to different routers to provide

1) increased speed

2) failover in case one router/port fails

Is this possible and briefly, how would it be done? I'm working with a vendor who'll do the actual config.
