A method and apparatus for transmitting inter-domain fault information are disclosed, wherein, the method includes: a service layer LSP determining that the protection or recovery of the service layer LSP is invalid; and the service layer LSP transmitting inter-domain fault information to a client layer of the service layer, wherein the inter-domain fault information is used for indicating that the protection or recovery of the service layer LSP is invalid; and the service layer LSP and the client layer LSP belong to different AS domains. The present invention allows a client layer LSP to learn in time that the protection or recovery of a service layer LSP has failed, so that the client layer LSP protects or recovers the service layer LSP in time, shortening the time of end-to-end service failure and improving the network survivability. |
