Re:true failover?

As per my observation, a home-made linux based failover router is meant to serve only an internal LAN and does not require to communicate with the upstream routers, since it is the ISP's router that directly communicates with the upstream routers using some specific routing protocol. Therefore, if any upstream router dies or goes down, it will be the ISP's router that will detect it first and the effect of it will be experienced by the Linux failover router which, consequently, will switch to the second route.
