    No but we need to wait for Jeff to commit his parallel routing 
    table improvements before we begin messing with the route table.
    It's very complex code.

    In the case of ifconfig aliases, I agree completely that we should
    allow netmask's other then  I would also like to have
    that capability for e.g. parallel routing.  The route table was never
    designed for duplicate masks so it won't be a trivial matter.
If I am understanding you right, the ability to have two interfaces on the 
same network?  Well that's possible with minor amount of code changing by 
use of Itojun's changes in KAME and NetBSD.

I have not done a port of it for the same reason that you outline.  It is 
vital that Jeff finishes his work on parallel routing without any hiccups 
before I start medeling in that part of the kernel.
