Detailed Description

Task that flushes (deletes) a specific neighbor entry.

Constructs and sends an RTM_GETNEIGH/RTM_NEWNEIGH-style request to remove the specified neighbor and processes the kernel's response.

Constructor & Destructor Documentation

NeighborFlushTask()

llmx::rtaco::NeighborFlushTask::NeighborFlushTask	(	SocketGuard &	socket_guard,
		uint16_t	ifindex,
		uint32_t	sequence,
		std::span< uint8_t, 16 >	address )

Construct a NeighborFlushTask to remove a neighbor entry.

Parameters

socket_guard	Socket guard used to send the request.
ifindex	Interface index.
sequence	Netlink message sequence number.
address	Address bytes to identify the neighbor.
