This is a bit of different problem, and therefore a bit of different solution. A better solution to the standby router issue is simply to have your hosts listen for the default route via RIP or OSPF. If they don't see updates from a particular router, it is assumed dead and your hosts switch to use the another router. You setup route priorities to force hosts to prefer a particular router. Also, with the new equal-cost routing patch for FreeBSD, FreeBSD will automatically balance traffic for routes with the same destination and same priority.
