After enabling DECnet routing, the interface MAC address turns to
something like this:
GigabitEthernet0/2 is up, line protocol is up
Hardware is BCM1250 Internal MAC, address is aa00.0400.0a04 (bia 000b.bffd.fc1a)
And you'll find
AA-00-04 (hex) DIGITAL EQUIPMENT CORPORATION
in the list. I don't know what 02-07-01 is, but I guess that could be
something similar: The OUI belongs to a company, but they don't use the
addresses to burn them into interface cards.
