Cisco redundancy Trunks to router?

Hi Everyone,

Need some advice.

I have two switches (3560s using only layer 2) and a 2811 router.

Between the two switches I have two x2 gigabit ethernet links running in a etherchannel.

I am also running two vlans. One for voice and one for data.

I want to run two trunks to the 2811. One trunk per switch to the router.

What is the best way to configure this on the router.

Usually if it was one trunk it would be two sub interfaces on that port with two IP address as gateways address.

I wanted to do this as a sort of backup redundancy type of thing but if I could get this working as a load balancing the two vlans (like s rapid spanning tree per vlan) that would be a plus as well.

Thanks in advance.
