description The invention relates to the technical field of IPv6 network security, in particular to an IPv6 neighbor discovery protocol security protection method and system based on SDN and P4 technologies, an SDN architecture is established in a target IPv6 network, a control plane and a data plane of a switch in the target IPv6 network are separated, and the SDN architecture is established in the target IPv6 network. The control plane is composed of a switch local controller and carries out MAC address self-learning according to data plane transmission information. The data plane is composed of a P4 data packet processor, and address information of a target IPv6 network host is collected in advance by using the P4 data packet processor; and for the request and notification message sent by the host, verifying the request and notification message data packet by using the pre-collected address information of the target IPv6 network host so as to filter the abnormal data packet, and safely forwarding the request and notif
