IPv6 Routing

IPv6 Routing is supported on the following platforms: s z

IPv6 (Internet protocol version 6) is the successor to IPv4. Due to the extremely rapid growth in internet

users and IP addresses, IPv4 is reaching its maximum usage. IPv6 will eventually replace IPv4 usage to

allow for the constant expansion.

This chapter provides a brief description of the differences between IPv4 and IPv6, and the Dell

Networking support of IPv6. This chapter describes the following, but is not intended to be a

comprehensive description of IPv6.

• Protocol Overview

• Extended Address Space

• Stateless Autoconfiguration

• IPv6 Headers

• Implementing IPv6 with FTOS

• ICMPv6

• Path MTU Discovery

• IPv6 Neighbor Discovery

• SSH over an IPv6 Transport

• Configuration Task List for IPv6

Protocol Overview

IPv6 is an evolution of IPv4. IPv6 is generally installed as an upgrade in devices and operating systems.

Most new devices and operating systems support both IPv4 and IPv6.

Some key changes in IPv6 are:

• Extended Address Space

• Stateless Autoconfiguration

Note: The IPv6 basic commands are supported on all platforms. However, not all features are supported

on all platforms, or for all releases. To determine the FTOS version supporting which features and

platforms refer toTable 22-2
