Title: PSEUDO NODE IDENTIFYING METHOD AND APPARATUS
Abstract:
A pseudo node identifying method comprises: a first intermediate system determines that protocol interface identifiers of at least two interfaces are identical, the two interfaces comprising a first interface and a second interface, the first intermediate system being connected with a third interface of a second intermediate system by means of the first interface, and the first intermediate system being connected with a fourth interface of a third intermediate system by means of the second interface; and the first intermediate system sets, according to a designated intermediate system (DIS) election regulation, a DIS election priority of the first interface as a minimum value, such that the second intermediate system is a designated intermediate system for determining a pseudo node protocol identifier. The method avoids occurrence of a plurality of identical protocol identifiers in a local area network, thereby improving the accuracy rate of topology calculation, and further reducing discarding of data traffic.
