Abstract

This document is a companion to the ION working group's architecture document, "IPv6 over Non Broadcast Multiple Access (NBMA) networks". It provides specific details on how to apply the IPv6 over NBMA architecture to ATM networks. This architecture allows conventional host-side operation of the IPv6 Neighbor Discovery protocol, while also supporting the establishment of 'shortcut' ATM forwarding paths (when using SVCs). Operation over administratively configured Point to Point PVCs is also supported.

Abstract

This document is a companion to the ION working group's architecture

document, "IPv6 over Non Broadcast Multiple Access (NBMA) networks".

It provides specific details on how to apply the IPv6 over NBMA

architecture to ATM networks. This architecture allows conventional

host-side operation of the IPv6 Neighbor Discovery protocol, while

also supporting the establishment of 'shortcut' ATM forwarding paths

(when using SVCs). Operation over administratively configured Point

to Point PVCs is also supported.

1. Introduction.

This document is an ATM-specific companion document to the ION

working group's, "IPv6 over Non Broadcast Multiple Access (NBMA)

networks" specification [1]. Terminology and architectural

descriptions will not be repeated here.

The use of ATM to provide point to point PVC service, or flexible

point to point and point to multipoint SVC service, is covered by

this document.

A minimally conforming IPv6/ATM driver SHALL support the PVC mode of

operation. An IPv6/ATM driver that supports the full SVC mode SHALL

also support PVC mode of operation.

2. Specification 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 RFC 2119 [16].

3. PVC Environments

When the ATM network is used in PVC mode, each PVC will connect

exactly two nodes and the use of Neighbor Discovery and other IPv6

features is limited. IPv6/ATM interfaces have only one neighbor on

each Link. The MARS and NHRP protocols are NOT necessary, since
