Address corresponding relationship sending method of layer 2 protocol utilizing link state routing

The invention aims at providing a method and a device for sending address corresponding relation information and updating media access control (MAC) lists in a data link layer protocol utilizing a link state routing, which are used for resolving the problems that requesting broadcast of address corresponding relation information in the data link layer protocol utilizing the link state routing is much in broadband occupation. By means of the technical scheme, address corresponding relation information of terminal equipment is stored in address corresponding relation information list of other network nodes besides an inlet network node, accordingly when address corresponding relation information requests are received, responses of the address corresponding relation information can be directly responded, the request does not need to be broadcasted, and broadband occupied by broadcast address corresponding relation information in the data link layer protocol utilizing the link state routing is reduced.
