Constructor & Destructor Documentation

◆ IAContext()

isc::dhcp::AllocEngine::ClientContext6::IAContext::IAContext ( )

Default constructor.

Initializes type_ to Lease::TYPE_NA and iaid_ to 0.

Definition at line 455 of file alloc_engine.cc.

◆ addHint()

void isc::dhcp::AllocEngine::ClientContext6::IAContext::addHint	(	const asiolink::IOAddress &	prefix,
		const uint8_t	prefix_len = `128`
	)

Convenience method adding new hint.

Parameters

prefix	Prefix or address.
prefix_len	Prefix length. Default is 128 for addresses.

Member Data Documentation

◆ changed_leases_

Lease6Collection isc::dhcp::AllocEngine::ClientContext6::IAContext::changed_leases_

A pointer to any leases that have changed FQDN information.

This list may contain old versions of the leases that are still valid. In particular, it will contain a lease if the client's FQDN has changed.

Definition at line 416 of file alloc_engine.h.

Referenced by isc::dhcp::Dhcpv6Srv::createNameChangeRequests().

◆ hints_

HintContainer isc::dhcp::AllocEngine::ClientContext6::IAContext::hints_

client's hints

There will typically be just one address, but the protocol allows more than one address or prefix for each IA container.

◆ ia_rsp_

Option6IAPtr isc::dhcp::AllocEngine::ClientContext6::IAContext::ia_rsp_

A pointer to the IA_NA/IA_PD option to be sent in response.

Definition at line 420 of file alloc_engine.h.

Referenced by isc::dhcp::Dhcpv6Srv::extendIA_NA(), and isc::dhcp::Dhcpv6Srv::extendIA_PD().

◆ iaid_

uint32_t isc::dhcp::AllocEngine::ClientContext6::IAContext::iaid_

iaid IAID field from IA_NA or IA_PD that is being processed

Definition at line 390 of file alloc_engine.h.

◆ old_leases_

Lease6Collection isc::dhcp::AllocEngine::ClientContext6::IAContext::old_leases_

A pointer to any old leases that the client had before update but are no longer valid after the update/allocation.

This collection is typically empty, except cases when we are doing address reassignment, e.g. because there is a host reservation that gives this address to someone else, so we had to return the address, and give a new one to this client.

◆ type_

Lease::Type isc::dhcp::AllocEngine::ClientContext6::IAContext::type_

Lease type (IA or PD)
