PIX Failover, 2 Inet BGP routers, different locations

[Bill CARTER]

I have a customer building redundant Internet connections. 2 sites are seperated by a T-1. Each site will have a BGP router running EBGP with provider and IBGP with each other. They want a PIX at each site running Failover between them. According to 6.3 docs, failover interfaces must be on the same IP subnet. Has anyone every tackled this scenario?

Not only does the failover interface have to be on the same subnet, but EVERY other interface on the PIX has to have a connection to the same interface on the other PIX, in the same subnet. I don't see how you could do this when they're remote.

The two PIX's send hello's out every interface to ensure they're all still up, plus they send stateful information over a separate interface. On a busy PIX you would delays in this stateful information which would lead to more problems.

Basically what I'm trying to say is that you don't want to/can't do this.
