It is not valid to assign the same IP address to two interfaces. (We actually sort-of support a configuration called a ``half-router'' where this is not true, but only one of the interfaces can be multiple-access; the others have to be point-to-point. I would just as soon not support this either, but enough people use it to make desupporting in politically impossible.) -GAWollman -- Garrett A.
