Subject Re: [Proposal] Minimise VR downtime during network update.
Date Tue, 11 Aug 2015 15:57:44 GMT
Hi Daan,

I am not aware of  the work done for rVPC networks.  I am still in the POC stage, will update
the FS or scope it down depending on 
the changes related to rvpc, If there are too many changes may be i will restrict this to
non vpc networks.

I will create a apache ticket fro this work.
