Whic one of these, is locally assigned unicast MAC address, when talking about
output format CSCO uses?

4000.0000.0000 (Local IXPs choice)
0200.0000.0000 (My money is here)

the second one. most significant byte is on the left, but within the
byte, most significant bits are on the right. so U/L bit is the second
one counting from the left.

02-07-01   (hex)                RACAL-DATACOM

good point, dunno.
