Hi, Few questions: 1] How does dead gateway detection happen in Linux? 2] I am using multipath default routes and I want the kernel to detect when a particular default route is down and stop using it. I would also like the kernel to detect when that particular default route is up and start reusing it. From the reading that I have done so far I realized there are two options. a] One option is to use Juliano's patches (http://www.ssi.bg/~ja/nano.txt). From what I understand Juliano's patches provide following. The patches let a static route be marked as 'dead' when it goes down. Also it detects that when the route is up and starts using it. However, it requires that we use NAT. I do not want to use NAT. In that case will his patches work for me? Another question regarding his patches is how does kernel detect when a route is dead? b] second option is put together a simple script which pings and find out when routes are dead and changes the multipath default routes accordingly. That is what I am doing now. I would like to know if there is a better option. I would appreciate if more pointers/information/options are provided for failover mechanism in mutipath default routes.
