The problem occurs when an app on this router establishes a tcp connection to some other app several hops away. The route caching code adds a static host route to the forwarding table. This is fine as long as nothing changes, but as soon as a downstream router has an interface change or a route change, this static host route is no longer valid. The routing demons, in this case gated running ospf , update the routes, but the static route is still there causing the tcp stream to fail. What I think I need is some way to disable the caching 'optimizations' for locally terminated connections. Can someone suggest some options ?
