<p>The present invention provides a method for inheriting an attribute of a FA in a multilayer network, this multilayer network adopts an upper layer signaling triggered model to set up the FA, and comprises: a path compute element returning information of a first attribute of each link on a FA LSP included in computed paths in a response message of a route inquiry to an upper layer head node initiating the inquiry, and this first attribute being a part of attributes which require constructing and obtaining according to corresponding attributes of each link on the FA LSP in attributes of the FA; this upper layer head node initiating connection setup according to this path; a head node on the FA LSP constructing the first attribute of this FA according to information of the first attribute of each link on the FA LSP included in a path message sent from a upstream node and storing the first attribute of this FA, and sending information of the first attribute of this FA to a tail node on the FA LSP by the path message; and c) the tail node on the FA LSP obtaining information of the first attribute of this FA from said path message and storing the first attribute of this FA. The present invention also provides a multilayer network.</p> |
