    Is this a real requirement? Ignoring the Bridge product, suppose that
    two departments each set up independent ethernets. They properly
    register their IP addresses so there is no conflict. Later they decide
    to attach the two segments together either directly or thru a repeater.

    This seems a common enough occurrence to me. If TCP/IP requires that
    they renumber all their hosts then this sounds like a significant
    flaw in the addressing and routing scheme.

Is it a flaw in the design of a rake that it does not perform very well
as a shovel?? The Internet architecture includes gateways to connect
different networks. One of the essential advantages of a gateway over a
level-2 bridge is the separation of address spaces. If you need a
rake, buy a rake, don;t complain that your shovel cannot be adapted.
Perhaps the moral is... beware of the glib tongues of shovel salesmen.
