On the subject IP networks I have available, the routers annouce the default route through RIP. The host has a RIP process and that“s all working fine: it does acquire a working default route automatically. The host has 2 NICs with 2 different IP address from the same network. So, in practice, it has 2 routes to the same gateway, but only one is in use at a given particular time. The problem is: If I disconnect the NIC that“s being used to reach the gateway, and after a while, the host doesn't begin to prefer to use the other NIC... The problem, I suspect, is that the routes continue to reach the RIP process (through the working NIC) and it doesn“t really care from what NIC does the information come from, and so, it doesn't introduce a penality (by timing out) on the route of the "broken" NIC. Any ideias? Thanks for your time, Joćo To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
