Dual default routes?

Hi,

I'm after a bit of help. My corporate internet connection has 2 separate /27 bit subnets, unfortunately they aren't contiguous. As part of the redesign I want both subnets to be available to route out to the internet, might as well as we are paying for them!

The way i'm told I can achieve this is by using dual default routes, can anyone explain how this would work, I assume one route would have a higher metric and would come in to play if the primary failed?

So something like this for example:

ip route-static 0.0.0.0 0.0.0.0 1.1.1.1
ip route-static 0.0.0.0 0.0.0.0 2.2.2.2 preference 200

Thanks in advance,

Matt.
