Hmmm, why are you getting /32's to begin with? If you're address scheme
is correct, there should be no reason for the /32 from Frame. I can see
that in Loopbacks, ISDN, but not from frame. never saw it myself.
Execpt!
If you have an overlapping address in another router/interface, I have
seen the router9s) generate host routes to try and make it work. But I
can't reproduce it off the top of my head.
If I somehow missed the point, please enlighten me ;-)
