i'm looking for pointers to any resources for doing failover on solaris boxes. i have an environment in which i'd like a pool of servers to use one of two solaris boxes as their gateway, the other box being in hot standby until a failure of the primary box occurs, at which time it would failover.
f.root-servers.net (192.5.5.241) is a virtual host on two different physical hosts. these hosts speak gated and inject a /32 route into ospf, which makes the /32 look dual homed. the exit gateways pick the first one they saw (or sometimes i adjust the costs manually). if the host that was picked as the path to the vhost dies, the exit gateways flip the route over to the surviving host. alteon, foundry, and radware make "layer 4 switch" boxes that do the same thing but add local load balancing so that both hosts can be up and serving at the same time. in this case the virtual host is in the L4-switch box which does its own remapping to physical hosts. -- Paul Vixie <paul@vix.com>
