Dear ns users, I would like to announce an IS-IS routing extension for ns. It has been developed at Telia Research, Sweden as a part of my master's thesis. Visit the homepage http://www.dtek.chalmers.se/~d96krisv/isisns/ for more information. The master's thesis which can be found on the homepage is recommended reading for anyone who wish to use isisns. Enjoy! /Kristian
