hi stefano, +ISIS-WG as this is now a WG-item. a comment n the 'V' flag - what is IMO missing is the clarification when and when not to use the 'V' flag. i.e. for which particular data plane - to play devils advocate: as generic as the draft is right now, the V-flag may be abused for prefix-SIDs on a MPLS data plane as an attempt to-reintroduce the notion of global labels, which as you may know i do reject. may i ask you to add some clarifying notes that V-flag=1 applies only for the Prefix SIDs assuming IPv6-SR dataplane. furthermore i am not really sure what the V-flag shall mean for Adjacency-SIDs. (the adjacency-SID always has been a label and never an index). thanks, /hannes On Jun 6, 2014, at 10:47 AM, Stefano Previdi (sprevidi) wrote: > Co-authors, > > this is the latest version we are ready to submit.
