6man O. Vautrin Internet-Draft Juniper Networks Intended status: Standards Track B. Lourdelet Expires: February 14, 2011 Cisco Systems, Inc August 13, 2010 Multi link PPP Support for an ipv6 address class identifier draft-vautrin-6man-ipv6-mlppp-id-00 Abstract This document specifies a new multi link protocol address class identifier. This new class will be able to contain an ipv6 address. Status of this Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

Introduction RFC 1990 [RFC1990] defines 6 different classes in its Endpoint Discriminator Option (from Class 0 to class 5). If a Multilink PPP is created in an ipv6 environment it would be possible to use the Class 1 address space and place the IPv6 address there as the MLPPP session ID. But the Class 1 has been deprecated and is thus not the right vehicle for an ipv6 address. This document propose the creation of a class 6 dedicated to ipv6 addresses. 2. Requirements Language 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 RFC 2119 [RFC2119]. 3. New IPv6 Endpoint Discriminator address class Per RFC 1990 [RFC1990], the Endpoint Discriminator Option is defined as such: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type = 19 | Length | Class | Address ... +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Figure 1 Vautrin & Lourdelet Expires February 14, 2011 [Page 3] Internet-Draft IPv6 MLPPP ID August 2010 The Endpoint Discriminator Option represents identification of the system transmitting the packet. The specification of the subfields are: Type 19 = for Endpoint Discriminator Length 3 + length of Address Class The Class field is one octet and indicates the identifier address space. Current values are assigned as follows: 0 Null Class 1 Locally Assigned Address 2 Internet Protocol (IPv4) Address 3 IEEE 802.1 Globally Assigned MAC Address 4 PPP Magic-Number Block 5 Public Switched Network Directory Number This document defines a new class of endpoint discreminator address: 6 Internet Protocol (IPv6) Address defined as: Class 6 - Internet Protocol (IPv6) Address Fixed Length: 16 Content: An address in this class contains an IPv6 host address as defined in RFC 2460 [RFC2460]. 4.
