Although most of them are stetic, I'd like to make the alias to the lo0 interface and let RIP announce the route for me. Also, the aliased IPs would be in another subnetwork. Is there any foreseeable problem in this approach ? ifconfig de0 inet 146.164.2.31 netmask 255.255.255.192 ifconfig de0 inet 146.164.63.4 netmask 255.255.255.192 ifconfig lo0 inet 127.0.0.1 # These are for a virtual subnet. ifconfig lo0 inet 146.164.63.193 netmask 255.255.255.255 alias ifconfig lo0 inet 146.164.63.194 netmask 255.255.255.255 alias ... To start plauing: I could not make routed export the routes for those addresses, but gated solved this problem using static routes entries. My system is currently a 2.1.0, but I plan to upgrade to 2.1.5 in the very near future.
