Lucy, Kamran, Sri and Mustapha Can each of you confirm to me that your MPLS-RT review comments has been satisfactorily addressed. I will start the working group adoption poll as soon as I have your¨resonses, /Loa On 2015-09-08 21:25, Kireeti Kompella wrote: > Hi All, > > Thanks all again for your comments. > > I've just posted a new version incorporating all your feedback.
