IPv6 Routing

Internet protocol version 6 (IPv6) routing is the successor to IPv4. Due to the 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

is not intended to be a comprehensive description of IPv6.

NOTE: The IPv6 basic commands are supported on all platforms. However, not all features are supported on all platforms, nor

for all releases. To determine the Dell Networking OS version supporting specific features and platforms, refer to Implementing

IPv6 with Dell Networking OS.

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

• Header format simplification

• Improved support for options and extensions
