I am the assigned Gen-ART reviewer for this draft. For background on Gen-ART, please see the FAQ at . Please resolve these comments along with any other Last Call comments you may receive.   Document: draft-ietf-multimob-pmipv6-ropt-07.txt Reviewer: Alexey Melnikov Review Date: 16 July 2013 IETF LC End Date: 3 July 2013 IESG Telechat date: 18 July 2013   Summary: Ready for publication as an Experimental RFC with some nits Major issues: None   Minor issues: In 5.1.2: Dynamic IP Multicast Selector Mode Flag:       This field indicates the subscription via MTMA/direct routing       mode.  If the (M) flag value is set to a value of (1), it is an       indication that the IP multicast traffic associated to the       multicast group(s) identified by the Multicast Address Record(s)       in this mobility option SHOULD be routed locally (subscription via       direct routing mode).  If the (M) flag value is set to a value of       (0), it is an indication that IP multicast traffic associated to       the multicast group(s) identified by the Multicast Address Record       in this mobility option(s) SHOULD be routed to the home network,       via the MTMA (subscription via MTMA mode).  All other IP traffic       associated with the mobile node SHOULD be managed according to a       default policy configured at the PMIPv6 multicast domain. The last sentence: I don't think you should use RFC 2119 SHOULD here. I think you are saying that this document doesn't affect all other IP traffic. So just use "is managed" instead of "SHOULD be managed". Is IANA Considerations section clear to IANA? I suggest you add at least the URI for the IANA registry. Is IANA registration policy compatible with the type of document (Experimental)? I can't check that, as I don't know which registry you are talking about.   Nits/editorial comments: In 3.3: acronyms PBU and PBA need to be expanded on first use. They are expanded further down in the document.
