DHCPv6 server configuration

Introduction to the DHCPv6 server

Application environment

As shown in
address management and network configuration. After obtaining the IPv6 prefix, the DHCPv6 client sends
an RA message containing the prefix information to the subnet where it resides, so that hosts on the
subnet can automatically configure their IPv6 addresses by using the prefix.
NOTE:
A switch serving as a DHCPv6 server assigns DHCPv6 clients IPv6 prefixes, but not IPv6 addresses, and
supports DHCPv6 stateless configuration to assign other configuration parameters.

Basic concepts

DHCPv6 multicast address
The multicast address FF05::1:3 identifies all DHCPv6 servers on the site-local network. The multicast
address FF02::1:2 identifies all DHCPv6 servers and relay agents on the link-local link.
DUID
A DHCP unique identifier (DUID) uniquely identifies a DHCPv6 switch (DHCPv6 client, server, or relay
agent).
