Document: draft-ietf-dhc-dhcpv6-unknown-msg-06.txt Reviewer: Suresh Krishnan Review Date: 2014/03/25 IESG Telechat date: 2014/03/27 Summary: This draft is almost ready for publication as a Proposed Standard but I do have a few comments that the authors may wish to consider. * Section 4.1 (b) The following text is unclear. "if the relay agent receives the message for which it is not the target according to the message type." The text that follows talks about new server-to-relay messages sent to the relay agent being forwarded back to the server. Such a message will not meet either of the conditions laid out in Section 4.1. The following text seems extraneous " However, this is not strictly necessary, since DHCP does not provide a signaling message for rejecting unexpected message types, and therefore DHCP servers are not expected to respond to such messages." What exactly is "this" referring to? The DHCP server is not responding anyway to such messages. * Section 4.2 The prescribed behavior here is contradicts the text in section 4.1 defining a valid message. Specifically, what happens when a relay receives an unknown message type for which it is the intended target. According to 4.1, the relay does nothing. According to 4.2 the relay forwards.
