Re: [dhcwg] Reminder - WGLC for draft-ietf-dhc-access-network-identifier-02 - respond by April 27, 2014

[Sheng Jiang <[e-mail]>]

I have reviewed this document. Overall, it targets to solve a real operation issue. I am not knowledge enough to review the requirements and contents for each access-network-identifier sub-option. So the below is only review from DHC protocol perspective and document writing.

The DHC protocol specific description in section 7, 8 and 9 are generally weak. In section 7, it is unclear when the option should be used, which sub-option should be used under what consideration, and what DHC message is involved. In section 8, how the relay agent include these option is intangibly described. Although RFC 3046, Relay Agent Information Option (82) was mentioned in Section 4, the associated behavior is missed. The RFC is not referred too. In Section 9, how server is behavior when receives these option is intangible. Particularly, the response in DHCPv6 message is wrong: the document state: “There is no requirement that a server return these options  and its data in a downstream DHCP message.” This is NOT compatible with existing DHC definitions, particularly, when the newly-defined option is added by relay agent. Some relevant quote list below:

In section 2.2, RFC3046, “DHCP servers claiming to support the Relay Agent Information option SHALL echo the entire contents of the Relay Agent Information option  in all replies.”

A few reference idnits need to be fixed too.

  == Missing Reference: 'RFC1035'
  == Unused Reference: 'RFC2434'

  ** Obsolete normative reference: RFC 2434 (Obsoleted by RFC 5226)
