DHCPv6 and Autoconfiguration


You can choose to configure the IP address and other network settings, such as the TFTP server, DNS server, domain, and name on an IP Phone manually or by using a router or a DHCP server to automatically assign the IP address and other network information. For more information on how the Auto IP Configuration and DHCPv6 settings determine where the IP Phone acquires its IPv6 address and other network settings, see the following table.

When the M-bit is set on the router, the O-bit is ignored. The phone can set its IPv6 address based on an IPv6 address received from a DHCPv6 server or the phone can acquire its IPv6 address through stateless address autoconfiguration.

When the M-bit is not set, you should set the O-bit on the router. The phone will then acquire its IPv6 address through stateless address autoconfiguration. The phone will not request an IPv6 address from the DHCPv6 server, but it will request other network configuration information.
