two default routes on the same interfaces

[mljevakovic]

How can I set up two default routes on the same interfaces (outside, PIX)? Can I do it with static routes? I mean

0.0.0.0 0.0.0.0 x.y.z.w1 1

0.0.0.0 0.0.0.0 x.y.z.w2 2

unfortunately pix can't handle this sort of scenario.

for more info, read "q. can i connect two different isps to my cisco secure pix firewall (for load-balancing)?"

If I understand well it means that is possible with OSPF? How can I do this?

My scenario:

Outside interface of PIX is on the same subnet as three routers (192.168.1.0/24) which have three different connections to Internet. What I want is in case that is failure I can forward traffic over other.

You need to run OSPF between the PIX and the routers and put the common LAN interface on area 0.

inject default routes automatically from the routers to the PIX using the "default information originate" command.. set different metrics for the routers, based on the primary/secondary/tertiary links connected to the router.

Check the command reference from the below URL:
