    Abstract: Embodiments of the present invention provide a route advertisement method, and controller, where the method is applied to a BGP-based routing network, a physical controller in the routing network is connected to multiple physical routers, and the method includes: receiving, by the physical controller, routing information reported by at least one physical router; obtaining a traffic path in which the at least one physical router is used as an egress router to transmit traffic to a destination router; generating a route for a physical router in the traffic path; and delivering the generated route to a corresponding physical router. In these embodiments, it is avoided that congestion occurs at an egress router, and a router that receives the traffic may generate a route for the router according to the traffic path so as to transmit the traffic to a next-hop router of the router without a need of recalculation.

    Abstract: A network device creates a virtual border gateway protocol (BGP) peer and the BGP peer is enabled all BGP capability data configured in the network device. A BGP monitoring protocol (BMP) module of the network device acquires the enabled BGP capability by using a BGP message. According to the solution of the embodiment, the network device obtains all BGP capabilities configured in the network device and sends all the BGP capabilities to a monitoring server, so that the monitoring server can fully understand actual capability supported by the entire network, further providing an effective basis for deployment of and decision on the entire network.

    Abstract: A method and apparatus are provided. The method includes: a first network device sends route information of a destination network device, where the route information includes a destination address of the destination network device, a primary next-hop address, and a backup next-hop address, the primary next-hop address includes a common address of the first network device and a second network device, for example, a loopback address, and the backup next-hop address includes an address of the first network device, for example, an IP address of the first network device. By using this method, when a fault occurs in a connection between the second network device and the destination network device, another network device may directly send a packet to the first network device according to the backup next-hop address, to ensure normal packet forwarding.
