Abstract: Embodiments of this application relate to the communication field, and disclose a method, a device, and a system for transmitting a node identifier, to reduce a limitation on delivery of an SR POLICY route and improve network performance The method includes: A forwarding device sends a node identifier to a controller. The forwarding device receives a first SR POLICY route from the controller, where a target attribute of the first SR POLICY route is the node identifier. The forwarding device determines that the node identifier matches the target attribute of the first SR POLICY route, and forwards a traffic packet according to the first SR POLICY route.

Abstract: This application provides an information processing method. A first communication apparatus is configured with a BGP EPE function, a BGP session is established between the first communication apparatus and a third communication apparatus, and no BGP session is established between the first communication apparatus and a second communication apparatus. In this case, the first communication apparatus may obtain, by using the third communication apparatus, a route advertised by the second communication apparatus. The next hop of the route is the second communication apparatus. After receiving the route, the first communication apparatus allocates a BGP peer SID, and stores a correspondence between the BGP peer SID and the next hop. When receiving a packet including the BGP peer SID, the first communication apparatus may forward the packet to the next hop based on the correspondence.

Abstract: A method is applied to a first network device, the first network device and a second network device have a BGP neighbor relationship, and the method includes: The first network device creates an SBFD session, where the SBFD session is an SBFD session corresponding to a BGP session between the first network device and the second network device, the first network device is an initiator of the SBFD session, the second network device is a reflector of the SBFD session, and the BGP session is a session created based on the BGP neighbor relationship. The first network device sends an SBFD packet to the second network device based on the SBFD session. The first network device determines a state of the BGP session based on a state of feedback by the second network device for the SBFD packet.

Abstract: A routing information processing method and apparatus. The method includes a first network device determines a first segment identifier corresponding to a second network device and a first locator. The first network device determines a second segment identifier corresponding to a third network device and a second locator. The first network device sends routing information that includes the first segment identifier and the second segment identifier. A fourth network device advertises mirror routing information specific to the first network device, where the mirror routing information includes the second segment identifier or the second locator.
