Abstract: The present disclosure relates to the communications field, and discloses a BGP logical topology generation method, and a device. The method includes: obtaining, by a controller, node information of a first forwarder and BGP session information of the first forwarder, and obtaining node information of a second forwarder and BGP session information of the second forwarder; and generating, by the controller, a BGP logical topology between the first forwarder and the second forwarder according to the node information and the BGP session information of the first forwarder, and the node information and the BGP session information of the second forwarder that are obtained. The technical solution provided in the present invention can implement collection of a BGP logical topology between forwarders by the controller, which is favorable for the controller to manage forwarders running the BGP protocol.
