Re: Last Call: 'RADIUS Delegated-IPv6-Prefix Attribute' to Proposed Standard (draft-ietf-radext-delegated-prefix)

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.
