Hi all In RFC1122 Section 3.3.1.4 Dead Gateway Detection, it describes how to tell if your gateway is down so as to switch to the other gateways. How does linux implement this? If a linux box has nothing other than direct interface route and 2 default routes, what situations cause linux to switch gateways? The obvious one is ARP failing. I've heard that windows keep a per gateway retransmit count, and will switch gateway of the TCP stack reports "too many" retransits. Does linux try to do anything clever to detect down gateways?
