Re: BCP for Private OUI / address assignments?

    Realistically, OUI space is pretty large for each L2 domain... Once it
    hits an L3 domain, you can repeat OUIs all you want... Pick some prefix
    set of bits that include "locally assigned" that is unique to your
    organization and you will operationally be fine. Or the last 8 bits of
    your host server's base MAC (hardware) address -- plenty of entropy there.

    Even when two or 10 organizations merge, unless you are merging them
    into the same tributary L3 domain, its not a problem...

    And if it is a problem for more than 1 or 2 virtual machines, I'm sure
    your organization is big enough to split that into another
    domain/vlan/what have you.

    Yes, its a nice idea to have a BCP that works without conflicts, but
    I don't see how this is legitimately going to affect anyone more than
    theoretically... unless someone's device is really bad at generating
    OUIs; all of this based on the cheap prevalence of L3 devices at the edge.
