IPv6 Addressing
IPv6 Addressing, applies to platforms c e s
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 discussion of the differences between IPv4 and IPv6, and Dell Networking’
support of IPv6. This chapter discusses the following, but is not intended to be a comprehensive discussion
of IPv6.
• Protocol Overview
• Extended Address Space
• Stateless Autoconfiguration
• IPv6 Headers
• Implementing IPv6 with FTOS
• FTOS and IPv6 Feature Support
• Path MTU Discovery
• IPv6 Neighbor Discovery
• QoS for IPv6
• IPv6 Multicast
• 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:
Note: The IPv6 basic commands are supported on all platforms. However, not all features are supported
on all platforms, nor for all releases. See Table 17-2to determine the FTOS version supporting which
features and platforms.
