"Reserved" bits can have any value. Routers need to _ignore_ them if they don't know what they mean (that is, if they're too old). They must _generate_ packages with the value zero at any time, but when forwarding, they must not touch them. Any implementation that does is not just broken, but was made by a braindead person (I refuse to call someone like that a "programmer") -- wouter dot verhelst at advalvas dot be "Human knowledge belongs to the world" -- from the movie "Antitrust"
