Abstract: Embodiments of the present invention disclose a method, a router bridge, and a system for TRILL network protection. An active RB node and a standby RB node share a virtual Nickname and a virtual MAC address, and construct a protection group. The active RB node, through the TRILL protocol, obtains a network topology and generates a forwarding path to perform forwarding of a data packet. When the active RB node is faulty, the standby RB node is raised to be active and the data packet is forwarded through the standby RB node, so that the time for fault recovery is shortened, thereby solving the problem that in an existing TRILL network when a root RB node is faulty, a long time for the fault recovery causes a service interruption and affects network performance.

Abstract: The present invention discloses an access control method, apparatus, and system, and belongs to the communications field. The method includes: receiving a virtual extensible local area network VXLAN request packet sent by an access device; parsing the VXLAN request packet to obtain an IP address of the access device and authentication information of a user; sending the IP address of the access device and the authentication information of the user to an authentication server, so that the authentication server authenticates the user; receiving an authentication result sent by the authentication server; and controlling the user according to the authentication result. According to the present invention, the user is authenticated according to access information of the user in a VXLAN scenario.

Abstract: This application provides a path switching method and a related apparatus. In the path switching process, an ECMP table includes a first ECMP index of a first path group and a second ECMP index of a second path group; when all paths in the first path group have failed, a path group identifier corresponding to the first ECMP index may be changed from valid to invalid in the ECMP table, indicating that all paths in the first path group are unavailable. In this case, a path group identifier corresponding to the second ECMP index is valid, indicating that the second path group includes an available path, thereby completing switching between an active path and a standby path. In this process, only an identifier corresponding to the ECMP index needs to be updated, and therefore, the time consumed is relatively short, and the path switching delay can be effectively reduced.
