IPv6 Introduction

Integration of IPv4 and IPv6

IPv6 has been designed in such a way that a smooth transition from IPv4 is possible. The most
effective way to ensure this is to use a dual IP stack. A node configured as a dual stack system
has both a 128-bit IPv6 address and a 32-bit IPv4 address, and so can communicate with nodes
running IPv4 and those running IPv6.
Another aspect of the transition is to tunnel IPv6 packets through an IPv4 network. IPv6 packets
are tunnelled simply by encapsulating the IPv6 packet within an IPv4 datagram, and identifying
that this datagram is an encapsulated IPv6 packet by giving the datagram a protocol value of 41.

IPv6 on your Switch

This section describes the switch's support for IPv6, and how to configure IPv6 on the switch.
Fundamental IPv6 features on the switch are:

Enabling IPv6

The switch's implementation of IPv6 is disabled by default. To enable IPv6 forwarding, use the
ipv6 forwarding command on page
Note:
To display information about IPv6 settings, use the

Because the switch implements IPv6 as a dual stack, implementing IPv6 does not affect IPv4
functionality.

The 6bone Network

The 6bone is an experimental virtual network of nodes that support IPv6 packets, tunnelled
together through the existing IPv4 Internet. Most of the nodes are workstations or similar
machines, with IPv6-capable operating systems. The theory of tunnelling IPv6 packets over an
IPv4 network is outlined in
The 6bone is part of the transition to IPv6. Its purpose is to provide an environment in which
IPv6 can be tested and procedures for IPv6 can be developed. When IPv6 is sufficiently
developed and being used widely, the 6bone will probably disappear.
