Hi WG, As discussed in the IETF110 meeting, we start a two weeks adoption call on draft-tgraf-ipfix-mpls-sr-label-type-07: https://datatracker.ietf.org/doc/draft-tgraf-ipfix-mpls-sr-label-type/ Please respond with your comments and thoughts on this draft. <tp> I struggle to make sense of the IANA Considerations. Usual practice is to start 'IANA is requested to .. ' which is a) polite b) easily changed to 'IANA has ...' when they have. There are two separate actions, or perhaps not. Usual practice is to have separate sections, one might be 3.1 IANA is requested to allocate four code points in the existing sub-registry "IPFIX MPLS label type (Value 46)" of the "IPFIX Information Elements" registry for IS-IS, OSPFv2, OSPFv3 and BGP Prefix-SID Segment Routing extension 3.2 IANA is requested to add one new "IPFIX Information Element" with a new sub-registry in the "IP Flow Information Export (IPFIX) Entities" name space. and if 3.2 makes no sense to you it may be because the I-D makes no sense to me!. Perhaps there is only one IANA Consideration. This I think needs to be fixed before adoption. Separately, 2. MPLS Segment Routing Top Label Type is all about justification and motivation which I think that the heading should reflect. ' Adding an additional layer into the MPLS data plane to above described use case.' is unclear to me ...'we get insight' .. is not the impersonal style that an RFC usually is Perhaps Introducing four new code points to information element mplsTopLabelType(46) for IS-IS, OSPFv2, OSPFv3 and BGP Prefix-SID, when Segment Routing with one of these four routing protocols is deployed, makes it possible to see what traffic is being forwarded, based on which MPLS control plane protocol except that is not quite right. These four are not 'MPLS control plane protocol' in the accepted sense of the phrase. Perhaps -2 Introducing four new code points to information element mplsTopLabelType(46) for IS-IS, OSPFv2, OSPFv3 and BGP Prefix-SID, when Segment Routing with one of these four routing protocols is deployed, makes it possible to see what traffic is being forwarded by one of these four protocols' HTH Tom Petch We will conclude on April 7, 2021.
