MAC address confusion

[Saku Ytti <saku+nanog () ytti fi>]

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)

http://standards.ieee.org/regauth/oui/oui.txt
02-07-01   (hex)                RACAL-DATACOM
A0-6A-00   (hex)                Verilink Corporation

In either case two of the lowest or highest bits of 1st octet seems to be
happily used to assign addresses. What am I missing here?
