Hi Martin, Good to hear from you. > I have only one request: From a Transport Area perspective, > it would be good to emphasize RFC 7510 and its details about > MPLS over UDP. Happy to accommodate this request. But what do you have in mind? There are references to 7510, in the Introduction and in the first two use cases in Section 2. Then, the packet forwarding procedures in Section 3.2 begin with a reference to 7510 as well. And there a couple more references in the document. Thanks, Adrian
