Two major points: 1) Can we please have a proper implementation report for this spec? 2) The document does not define a mandatory to implement encapsulation method. All methods mentioned after MUST's in section 4 are conditional on statements like "when tunneling is done", and "systems that implement". In other words, interop is not guaranteed. I would imagine that the spec would want to mandate at least the MPLS/LDP one.

Note: -04 was Last Called in idr in February, satisfying our desires for BGP changes to be checked by idr. The changes from -04 to -07 (other than the ones asked for in the idr last call) are minor and don't warrant another idr Last Call.

There probably shouldn't be a citation in the abstract.

The draft appears to recommend that a site use Unique Local addresses in preference to Global Unicast addresses, through its quoting of the unique local draft's text here: "They have the additional property that they will continue to work if the individual sites are renumbered or merged." Personally, I believe this would be contrary to good practice if the site were not already using Unique Local addresses, since it increases the administrative and routing burden. I do not ask the authors to share this view, but I do note that more direct recommendation one way or the other would be clearer.
