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
• Default DHCPv6 Server and Relay Values
• Configuring the DHCPv6 Server and Relay (Web)
• Configuring the DHCPv6 Server and Relay (CLI)
• DHCPv6 Configuration Examples
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 autoconfiguration
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.
