Configuring DHCPv6 Server and

Relay Settings

This chapter describes how to configure the switch to dynamically assign

network information to IPv6 hosts by using the Dynamic Host Configuration

Protocol for IPv6 (DHCPv6).
The topics covered in this chapter include:

DHCPv6 Overview

DHCP is a protocol that is generally used between clients and servers for the

purpose of assigning IP addresses, gateways, and other networking definitions

such as Domain Name System (DNS) and Network Time Protocol (NTP)

parameters. However, IPv6 natively provides IP address auto configuration

through IPv6 Neighbor Discovery Protocol (NDP) and through the use of

Router Advertisement messages. Thus, the role of DHCPv6 within the

network is different than that of DHCPv4 because DHCPv6 is not the

primary source for IP address assignment.
DHCPv6 server and client interactions are described by RFC 3315 [6]. There

are many similarities between DHCPv6 and DHCPv4 interactions and

options, but there are enough differences in the messages and option

definitions that there is no DHCPv4 to DHCPv6 migration or

interoperability.
