7 Configuring IPv6

This chapter describes the IPv6 features supported by Nokia IPSO and how to configure them on your system.

IPv6 Overview

IPv6 is the next generation IP protocol and is expected to replace IPv4, the current IP protocol. The Internet Engineering Task Force (IETF) formally began to work on the new protocol in

1994. IPv6 enhances IPv4 in many ways including:

„Expanded addressing capabilities

„Simplified header format

„Improved support for extensions and options

„Flow-labeling capability

„Plug and play autoconfiguration

The IPv6 implementation includes basic features specified in IPv6 RFCs and features that support IPv6-capable hosts in a network. IPv6 includes a transition mechanism that allows users to adopt and deploy IPv6 in a diffuse way and provides direct interoperability between IPv4 and IPv6 hosts.

IPSO supports the following features as specified in the corresponding RFCs:

„IPv6 Specification (RFC 2460)

„ICMP v6 (RFC 2463)

„Neighbor Discovery (RFC 2461, router only)

„Basic IPv6 Socket Interface (RFC 2553), except the following features:

„Compatibility with IPv4 nodes

„Translation of nodename to address

„Translation of address to nodename

„Socket address structure to nodename and service name

„IPv6 Addressing Architecture (RFC 2373)

„IPv6 Aggregatable Global Unicast Address Format (RFC 2374)

„IPv6 UDP support

„IPv6 TCP support
