   Hi group:
   
   I don't think this can be done, but I'll throw it out there anyway.
   
   Suppose you have a remote router with a BRI interface that dials into
   an Access Server. The remote router negotiates it's IP address (i.e.
   it's assigned from a pool on the Access Server). Is there any way to
   run a classful routing protocol (RIP/IGRP) on the remote router to
   advertise the LAN. The remote LAN and the ISDN interface are part of
   the same major network, so I think this can't be done. The remote LAN
   is a /24, and the BRI is of course a /32 as it's been negotiated.
   Maybe there's some router trickery that I'm overlooking.
   
   One way I've thought of to pull this off is to have a tunnel interface
   with a /24 mask built when the BRI comes up. This works, but what an
   ugly hack.
   
   Something out there I'm overlooking?
   -B
