I'm having problems with this kind of interface alias.  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 netmask
ifconfig de0 inet netmask
ifconfig lo0 inet
# These are for a virtual subnet.
ifconfig lo0 inet netmask alias
ifconfig lo0 inet netmask 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.
