Bob - RFC 3633 [2] suggests the use of Framed-IPv6-Prefix option to
carry
the customer prefix from the provisioning database through RADIUS
to the
DHCPv6 PD delegating router. That use of Framed-IPv6-Prefix
overloads other
uses of the attribute to carry the prefix to be assigned to the
link between
the NAS and the CPE. This new I-D defines a new RADIUS attribute
to be used
expressly for a prefix to be delegated to the CPE for use in the
network
behind the CPE.
Thanks for the explanation! I think it would be good if something
like the above text was added to the draft. The current text can be
interpreted in several ways and seems to allow other usage. For
example, the scenario you describe is cited as an example.
Note: I am not against do this at all, I just want the document to be
clear in it's intended usage.
Thanks,
Bob

FYI. Has anyone looked at this? From the Introduction:
1. Introduction
The Delegated-IPv6-Prefix is a RADIUS attribute [1] that
carries an
IPv6 prefix to be delegated to the user. For example, the
prefix in
a Delegated-IPv6-Prefix attribute can be delegated to another
node
through DHCP Prefix Delegation [2].
I infer from this that the intent is for a DHCPv6 server to get a
prefix from an Radius/Diameter authentication check it will later
delegate to the user. This seems OK to me, but it would also seem
to provide for another general way to delegate IPv6 prefixes. I
think that the draft needs more explination on it's intended usage.
Or is this an IPv6 version of something that exists in IPv4?
Comments?
