RADIUS Support for Proxy Mobile IPv6
draft-ietf-netext-radius-pmip6-01
Abstract
This document defines new attributes to facilitate Proxy Mobile IPv6
operations using the RADIUS infrastructure. The RADIUS interactions
between the Mobile Access Gateway and the RADIUS server take place
when the Mobile Node attaches, authenticates and authorizes to a
Proxy Mobile IPv6 domain. Furthermore, this document defines the
RADIUS-based interface between the Local Mobility Anchor and the
RADIUS server for authorizing received Proxy Binding Update messages
for the MN's mobility session. In addition to the mobility session
setup related interactions, this document defines the baseline for
the Mobile Access Gateway and the Local Mobility Anchor generated
accounting.

Internet-Draft RADIUS-PMIPv6 November 2010
1. Introduction
Proxy Mobile IPv6 (PMIPv6) [RFC5213] is network based mobility
management protocol which allows IP mobility session continuity for a
Mobile Node (MN) without its involvement in mobility management
signaling. A Mobile Access Gateway (MAG) represents the MN and is
authorized to send mobility management signaling messages on behalf
of the MN. Before the MAG is able to perform the required mobility
management signaling, it needs to know at minimum the Local Mobility
Anchor (LMA) address and the MN Identifier (MN-ID). This per MN
Policy Profile (PP) information is stored in a Policy Store (PS),
which may be local to the MAG or remote accessible, for example,
through an authentication, authorization and accounting (AAA)
infrastructure.
This document defines the RADIUS [RFC2865] based profile and the
corresponding attributes to be used on the AAA interface between the
MAG and the RADIUS server. This interface is used to download the
per MN Policy Profile from the remote Policy Store to the MAG, at the
point when MN attaches to a PMIPv6 Domain. Furthermore, this
document also defines a RADIUS-based interface between the LMA and
the RADIUS server for authorization of the received Proxy Binding
Update (PBU) messages for the mobility service session. The AAA
interactions defined in this document cover both deployment models,
the scenario when the MN connects via the Visited access network, and
the case when MN directly attaches in its Home network.
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
The terminology in this document is based on the definitions found in
[RFC5213] and [I-D.ietf-netlmm-pmip6-ipv4-support]. The following
additional or clarified terms are used in this document:
Network Access Server (NAS):
A device that provides the access service for a user to a network.
In the context of this document the NAS may be integrated into or
co-located with the MAG. The NAS device contains the RADIUS
Client function.
Xia, et al. Expires May 19, 2011 [Page 4]
Internet-Draft RADIUS-PMIPv6 November 2010
Home AAA (HAAA):
An Authentication, Authorization, and Accounting (AAA) server
located in MN's home network. In scope of this document the HAAA
corresponds to a RADIUS server that includes the role of the
PMIPv6 Policy Store.
Visited AAA (VAAA):
An Authentication, Authorization, and Accounting (AAA) server
located in MN's visited network. In this document the VAAA is the
AAA server that acts as a RADIUS Proxy when the MN moves or
attaches through the Visited network. The VAAA receives an
authentication (or accounting) request from an AAA client such as
a NAS, forwards the request to the HAAA server, receives the reply
from the HAAA, and sends that reply back to the AAA client,
potentially adding changes to reflect local administrative policy.
3. Solution Overview
This document defines the RADIUS-based AAA interactions on two PMIPv6
interfaces:
o between the MAG and the AAA, and
o between the LMA and the AAA.
The Policy Profile is downloaded from the corresponding AAA server to
the MAG during the MN attachment to the PMIPv6 domain, while the LMA
seeks authorization from the RADIUS server upon receiving the Proxy
Binding Update (PBU) messages for the mobility service session.
When a MN attaches to a PMIPv6 Domain, a network access
authentication procedure is started. The choice of the
authentication mechanism is specific to the access network
deployment, but could be based on the Extensible Authentication
Protocol (EAP) [RFC3748]. During the network access authentication,
the MAG acting as a Network Access Server (NAS) queries the HAAA
through the AAA infrastructure using RADIUS protocol. If the HAAA
detects that the subscriber is authorized for the PMIPv6 services,
the policy profile including the PMIPv6-specific information is
returned along with the successful network access authentication
answer to the MAG.
After the MN has been successfully authenticated, the MAG sends a PBU
to the LMA based on the MN's policy profile information. Upon
receiving the PBU, the LMA interacts with the HAAA, and fetches the
relevant portion of the subscriber policy profile and authorization

information for the mobility service session.
This document adds support for three distinct MN's mobility use
cases, taking into account the administrative domains to which the
attended MAG and the LMA belong to. The observed network topologies
are identified by following conditions:
1. the MAG and LMA are both in the home network,
2. the MAG and LMA are both in the visited network, or
3. the MAG is in the visited network while the LMA is in the home
network.
Figure 1 shows participating network entities for the PMIPv6 mobility
session which are located in the home network. The MAG and LMA
interact only with the HAAA.

4. Attribute definitions
4.1. MIP6-Feature-Vector
Diameter [RFC3588] reserves AVP Code space 1-255 as RADIUS attribute
compatibility space. The MIP6-Feature-Vector AVP (AVP Code 124)
defined in [RFC5447] is of type Unsigned64 and contains a 64-bit
flags field of supported mobility capabilities. This document
reserves a new capability bit according to the rules in [RFC5447],
and reuses the capability bits defined by [RFC5779]. The following
capability flag bits are used or defined in this document:
PMIP6_SUPPORTED (0x0000010000000000)
This is defined in [RFC5779]. When the MAG/NAS sets this bit in
the MIP6-Feature-Vector attribute, it is an indication to the
RADIUS AAA that the NAS supports PMIPv6. When the AAA sets this
bit in the response MIP6-Feature-Vector AVP, it indicates that the
Xia, et al. Expires May 19, 2011 [Page 8]
Internet-Draft RADIUS-PMIPv6 November 2010
AAA has PMIPv6 support. This capability flag bit can also be used
to allow PMIPv6 mobility support in a subscription granularity.
IP4_HOA_SUPPORTED (0x0000020000000000)
This is defined in [RFC5779]. Assignment of the IPv4-HoA is
supported by [I-D.ietf-netlmm-pmip6-ipv4-support]. When the MAG
sets this bit in the MIP6-Feature-Vector attribute, it indicates
that the MAG implements a minimal functionality of a DHCP server
(and a DHCP relay) and is able to deliver IPv4-HoA to the MN.
When the RADIUS server sets this flag bit in the response MIP6-
Feature-Vector attribute, it indicates that the AAA has authorized
the use of IPv4-HoA for the MN. When the bit is unset in the
responding MIP6-Feature-Vector, the AAA does not authorize
configuration of the IPv4 address.
LOCAL_MAG_ROUTING_SUPPORTED (0x0000040000000000)
This is defined in [RFC5779]. When a MAG sets this flag bit in
the MIP6-Feature-Vector, it indicates that routing IP packets
between MNs anchored to the same MAG is supported, without reverse
tunneling packets via the LMA or requiring any Route Optimization
related signaling. When the flag bit is unset in the responding
MIP6-Feature-Vector AVP, the AAA does not authorize direct routing
capability. The MAG and AAA SHOULD support this policy feature
per MN and subscription basis.
IP4_TRANSPORT_SUPPORTED (0x0000080000000000)
This document defines the new capability bit for negotiation of
the IPv4 transport support between the MAG and AAA. When the MAG
sets this flag bit in the MIP6-Feature-Vector, it indicates its
ability to use IPv4 transport (i.e., IPv4-based encapsulation) for
carrying IP traffic between the MAG and the LMA. If this flag bit
is unset in the returned MIP6-Feature-Vector AVP, the AAA does not
authorize the use IPv4 transport on the MAG-to-LMA tunnel.
The MIP6-Feature-Vector attribute is also used on the LMA to the
RADIUS AAA interface. Using this capability announcement attribute
it is possible to perform a simple capability negotiation between the
LMA and the AAA. Those capabilities that are announced by both
parties in the MIP6-Feature-Vector are known to be mutually
supported. Additionally, the LMA may use this mechanism for the
particular MN to check PMIPv6 feature permissions while authorizing
the received PBU against the AAA.

Internet-Draft RADIUS-PMIPv6 November 2010
4.2. Mobile-Node-Identifier
The Mobile-Node-Identifier attribute is of String and contains the
mobile node identifier (MN-Identifier, see [RFC5213]) in a NAI
[RFC4282] format. This AVP is used on the MAG to the RADIUS server
interface. The Mobile-Node-Identifier attribute is designed for
deployments where the MAG does not have a way to find out such MN
identity that could be used in subsequent PBU/PBA exchanges (e.g.,
due to identity hiding during the network access authentication) or
when the HAAA wants to assign periodically changing identities to the
MN.
The Mobile-Node-Identifier attribute is returned in the Access-Accept
message that ends a successful authentication (and possibly the
authorization) exchange between the MAG and the HAAA, assuming the
HAAA is also able to provide the MAG with the MN-Identifier in the
first place.

4.3. PMIP6-Home-LMA-IPv6-Address
Before the MAG can engage in Proxy Mobile IPv6 signaling with the
LMA, it should know the IP address of the LMA either by means of pre-
configuration, or by dynamically discovering it. After the MN has
been successfully authenticated, the MAG can retrieve the IPv6
address of the LMA by fetching MN's policy profile information from
the AAA.

4.4. PMIP6-Visited-LMA-IPv6-Address
Figure 1 shows the interactions between the MAG, LMA, and HAAA. When
the mobile node moves into the visited network, the MAG interacts
with the HAAA through a visited AAA, and a visited LMA may be
assigned by the visited AAA during the interaction.
This attribute MAY be sent by the MAG to the VAAA in an Access-
Request packet as a proposal by the MAG to allocate the particular
LMA for the MN. This attribute MAY be sent by the VAAA to the MAG in
an Access-Accept packet. If included in the RADIUS response, the
attribute carries the IPv6 address of the visited LMA being assigned
on the MAG for the specific MN.

4.9. PMIP6-Home-HL-Prefix
Mobile Node's Home Network Prefix (MN-HNP) is a prefix assigned to
the link between the MN and the MAG. The MN configures its IP
interface from its home network prefix(es). When the LMA is located
in the home network, PMIP6-Home-HL-Prefix attribute is used to
deliver the MN-HNP from the HAAA to the MAG. The low 64 bits of the
prefix MUST be set to all zeroes.
The PMIP6-Home-HL-Prefix attribute is also used on the LMA-to-HAAA
interface containing the prefix assigned to the MN. If the LMA
delegates the MN-HNP assignment to the HAAA, the attribute MUST
contain all zeroes address (i.e., 0::0) in the request message. The
attribute MUST be present in Access-Accept when the prior request
included it, and SHOULD carry the MN-HNP the HAAA assigned.

5.1. General
The MAG to the RADIUS server interface is used for downloading the
Policy Profile (i.e., for bootstrapping of the Proxy Mobile IPv6
mobility service session) when a MN tries to attach, authenticate and
authorize to a PMIPv6 domain. Whenever the MAG sends a RADIUS
request message to the AAA server, the User-Name attribute (1) SHOULD
contain the MN identity. At minimum, the home realm of the MN MUST
be available at the MAG when the network access authentication takes
place. Otherwise the MAG will not be able to route the RADIUS
Access-Request messages towards the correct AAA server. The MN
identity MUST be in Network Access Identifier (NAI) [RFC4282] format.

7. Accounting
7.1. Accounting at LMA
The accounting at the LMA to AAA server interface is based on
[RFC2865] and [RFC2866]. This interface must support the transfer of
accounting records needed for service control and charging. These
records should include (but may not be limited to): time of binding
cache entry creation and deletion, number of the octets sent and
received by the MN over the bi-directional tunnel, etc.
7.2. Accounting at MAG
The accounting at the MAG to AAA server interface is based on
[RFC2865] and [RFC2866]. The interface must also support the
transfer of accounting records which should include: time of binding
cache entry creation and deletion, number of the octets sent and
received by the MN over tge bi-directional tunnel, etc.
If there is data traffic between a visiting MN and a correspondent
node that is locally attached to an access link connected to the same
MAG, the mobile access gateway MAY optimize on the delivery efforts
by locally routing the packets instead of using reverse tunneling to
the mobile node's LMA. In this case, the local data traffic too MUST
be reported to AAA Accounting servers by means of RADIUS protocol.
7.3. Table of Attributes
The following table provides a list of attributes that may be

to the RADIUS server via one or more AAA brokers or RADIUS proxies.
In this case the LMA to the RADIUS AAA server communication relies on
the security properties of the intermediate AAA brokers and RADIUS
proxies.
