If we purchase an OUI, is there a mechanism within Quantum to only allocate
Mac addresses with that prefix ?

Hi Vinay,

 

I understand your concerns about conflicts with already assigned OUIs.

It is however my opinion that it is not up to the Openstack Foundation, but
to entities deploying Openstack, to buy MAC OUIs.

As regards Quantum, we should ensure the default MAC range we use is locally
assigned; unfortunately I do not know enough about nova-network.

Also, it is my opinion that a locally-assigned OUI would be sufficient for
many use cases, without the need for a globally assigned one.

 

Regards,

Salvatore

I was talking to Nachi and Gary during the Quantum design session about the
need to have a proper MAC OUI allocation scheme for Openstack development
folks. They suggested that I send it out for wider discussion on the mailing
list. 

 

It turns out that it would be useful for the Openstack foundation to apply
for a MAC OUI from IEEE that can be used for development purposes and
testing. This way we don't unwittingly use someone else MAC allocation. Here
are the details

The cost to get a OUI allocation is around $2000 dollars. Remember if we use
random MAC OUI,  the actual owners can assert their legal claim on the MAC
address in the event of a conflict now that we have support for more
sophisticated tunnels that allow connections from public and private clouds.


 

Comments welcome.
