Re: [nvo3] DRAFT Charter Update for Discussion

[Anoop Ghanwani <[e-mail]>]

It sounds like what is being conveyed by "centralized NVA control plane" is
that the NVO3 WG doesn't want to bother with how redundancy is achieved
for the NVA (i.e. we don't want to worry about the clustering protocol
regardless
of whether that is accomplished using BGP or something else).  If so, I
think
it would be better to state that explicitly.

Everything else needed to complete the solution is in scope --
encapsulation,
NVA-to-NVE control protocol, multicast handling, etc., and there may be
more than one solution specified for each of these.  The only other big
"if" is
whether or not we attempt to solve the inter-DC problem.  Do I have that
right?
