Internet-Draft IPv6 MLPPP ID August 2010
1. 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

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. Acknowledgements
None

6. Security Considerations
