The Dynamic Host Configuration Protocol for IPv6 (DHCPv6) provides a framework to assign IPv6

prefixes, IPv6 addresses, and other configuration parameters to hosts.

Basic concepts

1692BMulticast addresses used by DHCPv6

DHCPv6 uses the multicast address FF05::1:3 to identify all DHCPv6 servers on the site-local scope, and

uses the multicast address FF02::1:2 to identify all DHCPv6 servers and relay agents on the link-local

scope.

1693BDUID

A DHCP unique identifier (DUID) uniquely identifies a DHCPv6 device (DHCPv6 client, server, or relay

agent). A DHCPv6 device adds its DUID in a sent packet.

The DUID falls into many types. The device supports only the DUID based on link-layer address (DUID-LL)

defined in RFC 3315.

2884HFigure 364 shows the DUID-LL format, where:

• DUID type—The device supports the DUID type of DUID-LL with the value of 0x0003.

• Hardware type—The device supports the hardware type of Ethernet with the value of 0x0001.

• Link layer address—Takes the value of the bridge MAC address of the device.
