Hello: I have just submitted ftp://ftpeng.cisco.com/volz/draft-ietf-dhc-dhcpv6-subid-01.txt to hopefully address the IESG discuss items (https://datatracker.ietf.org/public/pidtracker.cgi?command=print_ballot &ballot_id=1836&filename=draft-ietf-dhc-dhcpv6-subid). The differences of significance from the -00 draft are below. - Bernie --- - The subscriber-id is an NVT ASCII [4] string. The semantic contents - of the subscriber-id field are of course provider-specific. This - specification does not establish any semantic requirements on the - data in the string. + The subscriber-id information is only intended for use within a + single administrative domain and is only exchanged between the relay + agents and DHCPv6 servers within that domain. Therefore, the format + of and encoding of the data in the option is not standardized and + this specification does not establish any semantic requirements on + the data. This specification only defines the option for conveying + this information from relay agents to DHCPv6 servers. + + However, as the DHCPv4 Subscriber-ID suboption [4] specifies NVT + ASCII [5] encoded data, in environments where both DHCPv4 [6] and + DHCPv6 are being used, it MAY be beneficial to use that encoding. --- - subscriber-id A NVT ASCII string. It MUST NOT be null - terminated. + subscriber-id The subscriber's identity. --- 4. DHCPv6 Relay Agent Behavior DHCPv6 relay agents MAY be configured to include a Subscriber-ID - option in relayed (RELAY-FORW) DHCPv6 messages.

How the + subscriber-id is assigned and the mechanisms used to configure it are + outside the scope of this memo. + 5. DHCPv6 Server Behavior This option provides additional information to the DHCPv6 server. - The DHCPv6 server, if it is configured to support this option, MAY - use this information in addition to other relay agent option data, - other options included in the DHCPv6 client messages, and physical - network topology information in order to assign IP addresses, - delegate prefixes, and/or other configuration parameters to the - client. There is no special additional processing for this option. + The DHCPv6 server MAY use this information, if available, in addition + to other relay agent option data, other options included in the + DHCPv6 client messages, and physical network topology information in + order to assign IP addresses, delegate prefixes, and/or other + configuration parameters to the client.

Security Considerations - See [1] section 21.1, on securing DHCPv6 messages sent between - servers and relay agents, and section 23, on general DHCPv6 security - considerations. + As the subscriber-id option is only exchanged between relay agents + and DHCPv6 servers, [1] section 21.1, provides details on securing + DHCPv6 messages sent between servers and relay agents.
