also bear in mind that these bits are different in t/r:
e/n: <ig><gl>xxxxxx.X.X.X.X.X
t/r: xxxxxx<ig><gl>.X.X.X.X.X (actually not quite this simple, but in general
this is right)
(<ig> = individual/group, gl = global/local)
also, a sniffer will, by default, decode ("Cisco-1f.3e.45", "3com-4c.5a.99",
etc.) the vendor-ID(Y.Y.Y = vendor-ID in mac address = Y.Y.Y.X.X.X). These
vendor IDs are less usefull in recent years due to the many mergers, buy-outs,
and company name changes.
To avoid any confusion I usaully use: 0000:XXXX:0000, where X = router number.
Another, "no longer a concern" thing to be aware of is that DecNet uses the mac
address so you need to configure the mac addr change first before configuring
DecNet.
