One of our customers is trying to set up a TCP-IP network on
a private X.25 backbone. Their network includes both Ultrix
and SUN hosts. Apparently, the SUN implementation treats the
X.25 link as a collection of point-to-point links, and they
have talked our customer into configuring a class C network
number for each virtual circuit. Now they want to merge all
of these class C nets into one virtual class B network by
a sort of reverse subnetting. Has anybody ever done such a
thing (reverse "sub"netting) ?
