We have two PIX firewalls for two different functions, not failover.
Both PIX outside interfaces are in the same VLAN with edge router interface.
The edge router gets the default route from the PE router and distributes it to the intside on both firewalls.
At the moment there are two proccesses in each PIX, proccess 1 on the outside interface and process 2 on the inside interfaces of each PIX
The default route has to be dynamic for our failover scenario.
One PIX seems to be working by distributing the default to the inside, but the other PIX is not and causes problems with the dynamic routing.
Has anyone ever run across this type of scenaro and have some input on the best way to do this?
Any input would be appreciated.

What version? Any config you can share?

ver 6.3 on both PIXs:
This PIX is working and has adjacentcy, but looking at the "show ospf interface" the process 2 has no interfaces in it, but it does have adjacentcy with edge router and internal devices.

This PIX is not forming adcancentcy with edge router, but I don't think I need to really advertise from this PIX, all I need is to get the default router to it and the inside networks to it.

Sorry, the configs should look like this to match the drawing.
Would it be better to do some distribution in this scenario?
