Default Routing

I'm running EIGRP on my core. I currently have a default gateway pointing to the inside interface of my firewall. I'm looking to Run Two seperate firewalls on my network. I plan on basically swapping out the old with the new but for the mean time i'd like a way to run both at the same time. Maybe have a majority of my traffic going over the Old firewall while limited amount going over the new firewall. I feel like I know this already but i'm stumped. Anyway this can be done and if so How abouts do i do it. Can I configure 2 default routes?

Load balance, if unequal costs use the variance command.

Even if it's for a static Route, not just EIGRP?

It's actually a default route. So right now it goes:

S* 0.0.0.0/0 [1/0] via 192.168.100.2

I'd like to add another default route for all traffic to also go over the ASA. 192.168.100.2 is the inside interface of the PIX firewall. I'd like to add 192.168.200.2 which would be the inside interface of teh ASA.

I am pretty sure it will, but if it won't you could also redistribute the static routes into EIGRP, use a route-map to set the Administrative distance to a low value and use the same map to set the static routes to a higher value... A bit backwards way to go about it though. But don't quote me on that, I am pretty sure it would work, but have never tried it.

If you build two static routes the router will load balance between them by default. You will probably run into an issue of traffic flowing out over both links, but incoming traffic going over only one link if this is the only step you take.
