The first question would be, why do you need a second router
connecting to the same ISP? Are you looking for failover the routers,
or load balancing on the circuits?
Secondly, the PIX will only allow ONE route statement per network. So
if you have one "route outside 0 0 (ip)" statement, and try to add
another with the same network, the PIX will generate an error as if
you typed it wrong. The same holds true for any network. If there's
a numerical overlap, that happens.
Keep in mind that the PIX is not a router, and not designed to be
one. It's a firewall.
If possible for what you're trying to accomplish, I'd suggest the load
balancing on the router (two static routes will get addressed in a
round robin fashion for load balancing). otherwise, if you want
router redundancy, look at doing HSRP on the routers. just a
thought....

Subject: load balance outof PIX
Hi, all. I have a scenario where I have a lan whose deafult
gateway is a PIX to get to the net. (Actually 2 running failover). The
PIX outside then defaults to one internet router.
I'm adding a second router to the same ISP and want to load
balance out to the net from the PIX. I can't think of a way to do this
directly from the PIX (my reading says PIX doesn't support dynamic
routing or dual defaults, but hopefully I read wrong!) without putting
a third router in between the pix and the 2 ISP routers and put 2
defaults in that router or run a routing protocol bewteen the 2 isp
routers and the third router and advertise deafults from the 2 isp
routers.
First, does anyone from their experience know of a way to do this
without the third router?
If not, if I use dual static defaults, if one of the routers goes
down, the route will still be in there so I'm thinking if I have to go
with the third router having it receive dynamic defaults fron the ISP
routers is best.
Thanks!
