Chapter 4 IPv6 address configuration
72
Introduction
DHCPv6 protocol is used to automatically provision/configure IPv6 capable end points in a local
network. In addition to acquiring an IPv6 IP address for the WAN interface and its associated
LAN/WLAN clients, the devices are also capable of prefix delegation.
The Routers devices support the following types of modes of IPv6 addresses:
Stateless DHCPv6
Statefull DHCPv6
Table 78 IPv6 Modes
Mode
Description
Stateless
In Stateless DHCPv6 mode, the Routers devices listen for ICMPv6 Router
Advertisements messages which are periodically sent out by the routers on the
local link or requested by the node using a Router Advertisements solicitation
message. The device derives a unique IPv6 address using prefix receives from the
router and its own MAC address.
Statefull
In Statefull DHCPv6 mode, the client works exactly as IPv4 DHCP, in which hosts
receive both their IPv6 addresses and additional parameters from the DHCP server.
