VDC 1 - is this for admin vdc only?

[s.lachica]

Hi,

I would like to ask expert's opinion about this: We are implementing OTV at our N7K at the distribution layer. Documentations says that OTV and SVI routing cannot happen at the same time, so we allocated 1 vdc just for the OTV functionality. My question however is this: can we use vdc 1 as the OTV vdc, instead of allocating a new vdc (vdc4 for example), so as not to waste any vdcs. We have heard from our colleagues that vdc1 should only be used as admin vdc and not do the routing/switching stuff, so we always left vdc1 not a part of the production network, but serves only as administration vdc. We just like to know how true is this?

Many Thanks,

Sonny

Sonny-

Best practices is to use one VDC for Admin. Functionally speaking you can use it for routing traffic, so if you have to do it you can.

FYI - The new Supervisors now come with a "built-in" Admin VDC

not recommended to have ADMIN VDC to be used in production. there are certain things which are still used from default or admin vdc, such are some of the queuing configuration etc. its is not perfect to use it to have some traffic.
