I have a situation whereby a I want to implement redundancy. I have two wireless links with the wireless devices connected to two routers. Behind each router there is a firewall and behind the firewalls there is a router that will make the routing decision according to the availability of the link. I thought that I could easily implement this using floating static routes however the routes in router A (please see diagram below) are never changed if the failure is upstream say between router B and the wireless device. How would one implement failover in such a situation?
Please note that the firewalls are doing NAT.And no BGP currently running all routes are static.
