Ah, foolish me to imagine that any useful behavior could be expected from all that FDDI station management hair. Forget I even brought it up. > It is distant topology changes that trash ideas like bridges between > the primary and secondary rings, or single IP-network for both rings. The idea of putting single-MAC stations on the secondary ring is what should be trashed. (The idea of dual-MAC stations is also regrettable, in my humble opinion.) I fear that FDDI will be a case of "too much, too late." Grumpily yours, Steve
