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.
