A tunnel protecting method and device based on shared tunnels, the method comprising: configuring a shared work tunnel and a shared protection tunnel to form a protection group; periodically transmitting packets on the shared work tunnel and shared protection tunnel, detecting the status of the shared work tunnel and shared protection tunnel; when detecting changes in the status of the shared work tunnel and shared protection tunnel, performing a shared tunnel switching operation on the tunnel protection group. The technical solution of the present invention saves resources used for tunnel protection group switching, reducing bandwidth resources and computation resources used by devices. |
