  1. RADIUS extensions for PCP draft-maglione-pcp-radius-ext-02 R. Maglione – Telecom Italia D. Cheng – Huawei Technologies

  2. Motivations • draft-bpw-pcp-dhcp defines DHCP and DHCPv6 options which can be used to provision a PCP Server reachability information (FQDN of a PCP Server) • In a broadband network, customer information is usually stored on a AAA/RADIUS server and DHCP/DHCPv6 is used to populate user's configuration information • This document specifies a new RADIUS attribute to carry FQDN of a PCP server • A similar approach for provisioning the FDQN of the AFTR is already defined for DSLite in draft-ietf-softwire-dslite-radius-ext

  3. DHCPv6 ( … Option_PCP_Server) DHCPv6 based PCP Configuration DHCPv6 ( .. Option_PCP_Server ) RG NAS DHCPv6 Server PCP Client DHCPv6 Client PCP Server

  4. DHCPv6 ( Option_PCP_Server) RADIUS + DHCPv6 based PCP Configuration NAS translates PCP-Server-Name Radius Attribute into DHCPv6 option AAA Radius Server User profile: Username pwd Delegated-prefix ... PCP-Server-Name DHCPv6 ( ..Option_PCP_server ) RG Access-Accept ( .. PCP-Server-Name) Access-Request NAS: DHCPv6 Server NAS: RADIUS Client PCP Client DHCPv6 Client PCP Server

The NAS shall use the name returned in the RADIUS PCP-server-name attribute to populate the PCP Server FQDN DHCP Sub-Option in IPv4 addressing context, or the PCP Server FQDN DHCPv6 Option in IPv6 addressing context
