摘要： A method for advertising routing information by a routing device includes: checking whether a routing device is active; by the routing device, generating routing information, and marking the routing information with a check result; and advertising the routing information. With the present invention, a route attribute of routing information is set, so that the routing information can reflect the active or standby state of the active routing device and standby routing device; after the routing information is advertised, the routing of a remote routing device is affected. Thus, the remote routing device always selects the active routing device to forward packets, which ensures the reachability and connectivity of the network.
