Failover between LANs

I currently have 2 identical LANs connected via T1 (NY & Chicago) Each site has a core router, ISP router and PIX 515. I want to be able to dynamically failover between the 2 PIXs if either one goes down or the ISP goes down and re-route the internet traffic accordingly. I am currently doing this manually. Any suggestions greatly appreciated...

Re: Failover between LANs

One way of doing this is to (assuming you are running BGP with your ISP) run BPG through your PIX in each site. This would dynamically alter your internal routing table to reflect if one of the ISP connections went down. You would also have to ensure that both ISP's are advertising your address space to allow reachability back to you from both. I assume this is already being done if you are able to manually change now.

See the following link for BPG through PIX configuration examples.

Hope this helps,

Don
