Abstract: A first network device includes a processor and a memory having instructions stored thereon that, when executed by the processor, cause the first network device to: obtain a first virtual private network (VPN) route sent by a second network device. The first VPN route includes first identification information that uniquely identifies a first VPN instance in the second network device. The first network device is also caused to generate a second VPN route according to a second VPN instance accessing a third network device and the first VPN route. The second VPN route carries second identification information and routing information of the first VPN route. The second identification information uniquely identifies the second VPN instance in the third network device. The first identification information is different from the second identification information. The first network device is further caused to send the second VPN route to the third network device.

Abstract: Embodiments of this application disclose a routing method and a related device. When a first network device determines that a preset first condition is met, the first network device sends a request message to a second network device, to request a route reaching at least one another network device. In response to the request message, the second network device sends a route message to the first network device serving as a traffic sender, where the route message carries the route reaching the at least one another network device, and both the first network device and the another network device are directly or indirectly connected to the second network device.

Abstract: This disclosure discloses a method, device, and system for determining a route leak. The method includes: receiving, by a network monitoring device managing a first autonomous system, an extended BMP packet sent by a first border node of the first autonomous system and an extended BMP packet sent by a second border node of the first autonomous system. The method includes determining, based on the extended BMP packet sent by the first border node and the extended BMP packet sent by the second border node of the first autonomous system, a receiving relationship of a route prefix received by the first border node from the second autonomous system, and a sending relationship of the route prefix sent by the second border node to a third autonomous system. The method further includes determining, based on the receiving relationship and the sending relationship, whether the route prefix is leaked.

Abstract: The disclosure discloses a method. The method includes: determining, by a control node, routing entry information of a service function forwarding node in a SFP in the SFC, where the routing entry information records a mapping relationship between route prefix information and next hop information, the route prefix information includes a SPI and a SI, the SPI is used to identify the SFP, the SI is used to identify a location of the service function forwarding node in the SFP, and the next hop information is used to indicate a next hop node of the service function forwarding node in the SFP; and sending, by the control node, the routing entry information to the service function forwarding node, where the routing entry information is used by the service function forwarding node to generate a forwarding table used to instruct the service function forwarding node to forward a packet.

Abstract: A route processing method, a device, and a system, where the method includes: a network virtualization edge (NVE) device set including at least two NVE devices includes a common Virtual Extensible Local Area Network (VXLAN) Tunnel Endpoint (VTEP) address. The common VTEP address is used to identify a common VTEP, and the common VTEP is deployed on each NVE device in the NVE device set. In addition, each NVE device in the NVE device set includes a VTEP address, and the VTEP address is used to identify a VTEP included in a corresponding NVE device. An NVE device in the NVE device set establishes a VXLAN tunnel between the NVE devices in the NVE device set based on a VTEP address and the common VTEP address using an inclusive multicast Ethernet tag (IMET) route.
