Sorry, "bridges" as that word is used by DEC, the INTERNET world
and other significant portions of the free world does NOT deal
with the network layer.  Only through the datalink layer.

Even a quick look at DEC's marketing literature, let alone a technical
understanging show's that DEC's bridges are independant of protocol.
