The various states DAD may be in for an address.

Variants

Assigned

The address is assigned to an interface and can be considered bound to it (all packets destined to the address will be accepted).

Fields

ran_dad: bool

Indicates whether the address is assigned because DAD completed successfully, or because DAD was disabled and skipped.

Announcing

Like Self::Assigned, but the DAD engine is announcing to the network that we are using this address.

This state corresponds to the announcing described in RFC 5227 section 2.3 and as such only applies to IPv4 addresses. The IPv6 DAD specification (RFC 4862 section 5.4) does not define an announcement period.

Fields

timer: BT::Timer

The timer used to schedule DAD operations in the future.

ip_specific_state: I::AnnouncingState

Announcing state specific to the given IP version.

Tentative

The address is considered unassigned to an interface for normal operations, but has the intention of being assigned in the future (e.g. once Duplicate Address Detection is completed).

Fields

dad_transmits_remaining: Option<NonZeroU16>

The number of probes that still need to be sent. When None, there are no more probes to send and DAD may resolve.

timer: BT::Timer

The timer used to schedule DAD operations in the future.

ip_specific_state: I::TentativeState

Probing state specific to the given IP version.

probe_wait: Option<Duration>

The (optional) delay to wait before starting to send DAD probes.

Uninitialized

The address has not yet been initialized.

Trait Implementations
