Re: a routing question

It sounds like you need Router A to recognize when it should no longer use
it's static default route, remove it, and then use the route towards B. You
can create an SLA Tracker and tie it to the route. One thing you would watch
out for is that whatever you track through the firewall is not reachable
through Router B, otherwise the tracker would pass and the route would come
up again. Although, maybe you could tweak the tracker to differentiate...Any
other ideas?
