DHCPv6 Introduction

This chapter describes the Dynamic Host Configuration Protocol for IPv6 (DHCPv6) client
support provided by your switch, including sample DHCPv6 client configuration.

This chapter also includes sample configurations to configure your switch for DHCPv6
Relay.

DHCPv6 is specified in RFC 3315 “Dynamic Host Configuration Protocol for IPv6 (DHCPv6)”

See the section

DHCPv6 Messages

for the sequence of messages sent and received

between DHCPv6 Servers and DHCPv6 Clients and brief descriptions of the messages.

For the syntaxes, parameters, descriptions, defaults, and examples for all of the commands
used in sample DHCPv6 configurations, refer to

Chapter 66, DHCP for IPv6 (DHCPv6)

Commands

for the DHCPv6 Client commands.

DHCPv6 for IPv6

DHCPv6 is used to delegate IPv6 prefixes and to allocate IPv6 addresses. It offers stateful
address autoconfiguration, and complements Stateless Address Autoconfiguration
(SLAAC) described in RFC 2462, IPv6 Stateless Address Autoconfiguration. Stateless
Address Autoconfiguration (SLAAC) allows an IPv6-aware device to be plugged into a
network, and given an IPv6 address prefix without manual configuration.

DHCPv6 Clients first use RA messages to auto-configure themselves with any default
IPv6 route(s) via gateway router(s).

Interface addresses can also be automatically configured that are derived from
delegated prefix information.

See the section

“DHCPv6 Messages” on page 65.3

for solicit message information.

DHCPv6 RFCs

See the below list of DHCPv6 related RFCs:

RFC 3315 Dynamic Host Configuration Protocol for IPv6 (DHCPv6)
Stateful DHCPv6 - DHCPv6 has been standardized by the IETF through RFC 3315.

RFC 3646 DNS Configuration Options for DHCPv6.

RFC 3736 Stateless Dynamic Host Configuration Protocol (DHCP) Service for IPv6
Stateless DHCPv6 is a combination of IPv6 Stateless Address Autoconfiguration
(RFC 4862) and Dynamic Host Control Protocol for IPv6 (RFC 3315). It is a counterpart
to IPv6 Stateless Address Autoconfiguration, and can be used with or without IPv6
Stateless Address Autoconfiguration to obtain configuration parameters.

RFC 4841 Neighbor Discovery for IP version 6 (IPv6).

RFC 4862 IPv6 Stateless Address Autoconfiguration.

RFC 5007 DHCPv6 Leasequery.

Note

The IPv6 addresses shown use the address space 2001:0db8::/32, defined in RFC
3849 for documentation purposes. These addresses should not be used for
practical networks (other than for testing purposes) nor should they appear on
any public network.
