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) ? / Lars Poulsen Advanced Computer Communications
