okie, lets take the OSPF out for a while......
if I have a "unix" machine with 2 NICs as my gateway for a network....
and both those NICs are in the same network...
and on each node/PC i configure the 2 IP addresses of each NIC as the
what is wrong with that.....fine, you may say "one NIC may be preferred for
traffic coming into this LAN"...but logically if the kernel code is fine, it
should support NIC load balancing...right?
