Cisco 2611 with Two T1 from two ISPs

Would it be possible to have two internal t1 csu/dsu wic interfaces
each going to a separate ISP and basically use it as two logical
routers sending data from one ethernet interface to one T1 and the
other ethernet interface to the other.

I am trying to have 2 ISPs comming in for fault tolerance and load
balancing for my outgoing traffic as well as incoming traffic
including traffic to my 3005.

The way I pictured it I would have ATT come into one 2611 and MCI come
into a second 2611. Behind that I would have a Radware linkproof
loadbalancing appliance and behind that I will have a PIX 515e. In the
dmz I would have my 3005 and a FTP server and the internal interface
of the pix would go to my LAN of course.

Could I possibly do this using 1 2611 instead of two? The only
problem I would see is the routers default gateway.

 

Why one 2611 if you are after high availibility, isn't the 2611 a single
point of failure then ?

Yes, you can do this with policy routing.

interface EthernetX
ip policy default-att
interface EthernetY
ip policy default-mci

route-map default-att permit 10
set default interface SerialX

route-map default-mci permit 10
set default interface SerialY

 

The reason for one 2611 is to get me through budgeting issues untill January.
