Either baz =or foo are advertising a black hole and should fix their maps. = According to the maps, it is *not* doing a `wrong thing', but =is only reflecting the bogosity in the maps written by either =the administrator at site foo or site baz. The usual case here is that either foo or baz talks to a machine named bar which is NOT advertised in the maps. It has been a clear Usenet policy that every site need not advertise every machine they talk to. It has also been a clear policy that sites should not list every local machine (heaven help us if they did). In the perfect world, all machines and users and SOFTWARE would understand and only use domain routing. The world, currently, is not constructed that way. As Paul said, rutgers is RUDE. -- * * O Larry Blair ames-----\ * * O VICOM Systems Inc. pyramid---\ * * O 2520 Junction Ave. uunet!ubvax!vsi1!lmb * * O San Jose, CA 95134 sun-------/ * * O +1-408-432-8660 +1-800-538-3905
