[dhcwg] New draft on DHCPv6 Relay Information Option and RADIUS Attributes sub-option

Dear all,

We have submitted a new draft on DHCPv6 Relay Information Option and RADIUS 
Attributes sub-option last week. It's already available from the ietf site

http://www.ietf.org/internet-drafts/draft-droms-dhc-v6-relayopt-00.txt

but I have not seen the official announcement so far.

The draft basically carries over similar capabilities, namely,
RFC 3046 and draft-ietf-dhc-agentopt-radius-08.txt
from DHCPv4 to DHCPv6,  with initial use cases targetting for
the 3GPP2 environment.

Comments are welcome.

Regards,

Wing

Abstract

    This document introduces the capabilities of the DHCPv4 Relay Agent
    Information Option in RFC 3046 and the corresponding RADIUS-
    Attributes Sub-option to DHCPv6. In particular, the document
    describes a new DHCPv6 option called the Relay Agent Information
    option which extends the set of DHCPv6 options as defined in RFC 3315
    and 3376. Following its DHCPv4 counterpart as defined in RFC 3046,
    the new option is inserted by the DHCPv6 relay agent when forwarding
    client-originated DHCPv6 packets to a DHCPv6 server. Servers
    recognizing the Relay Agent Information option may use the
    information to implement IP address or other parameter assignment
    policies.  The DHCP Server echoes the option back verbatim to the
    relay agent in server-to-client replies, and the relay agent strips
    the option before forwarding the reply to the client. The Relay Agent
    Information option is organized as a single DHCPv6 option that
    contains one or more "sub-options" that convey information known by
    the relay agent.  A RADIUS Attributes Sub-option, following its
    DHCPv4 counterpart, is also defined.
