By limiting the number of addresses, a network administrator can limit the

other routers.

Bridging operates on physical network addresses (such as Ethernet
addresses), rather than logical addresses (such as DECnet addresses). From
the standpoint of DECnet networking, router interfaces which are set to
bridge DECnet between themselves appear as a single logical entity.

Thus, a router’s “DECnet Bridge Group” is made up of all of the physical
