DHCPv6
Mode

Router Controlled

: Selecting this option means that DHCPv6 is controlled by the

Managed (M) and Other (O) flags received in IPv6 router advertisements. When a
router advertisement is received, the NMC checks whether the M or the O flag is
set. The NMC interprets the state of the M (Managed Address Configuration Flag)
and O (Other Stateful Configuration Flag) "bits" for the following cases:
• Neither is set: Indicates the local network has no DHCPv6 infrastructure. The

NMC uses router advertisements and manual configuration to get addresses that
are not link-local and other settings.

• M, or M and O are set: In this situation, full DHCPv6 address configuration occurs.

DHCPv6 is used to obtain addresses AND other configuration settings. This is
known as DHCPv6 stateful. Once the M flag has been received, the DHCPv6
address configuration stays in effect until the interface in question has been
closed. This is true even if subsequent router advertisement packets are received
in which the M flag is not set.
If an O flag is received first, then an M flag is received subsequently, the NMC
performs full address configuration upon receipt of the M flag

• Only O is set: In this situation, the NMC sends a DHCPv6 Info-Request packet.

DHCPv6 will be used to configure “other” settings (such as location of DNS
servers), but NOT to provide addresses. This is known as DHCPv6 stateless.
