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.
Thanks
Suresh
