    Abstract: A method includes: establishing, by a first network device, a first BMP session with a second network device, and establishing a second BMP session with a third network device; receiving a first BGP route set sent by the second network device, where the first BGP route set includes a BGP route sent by the second network device to the third network device; receiving a second BGP route set sent by the third network device, where the second BGP route set includes the BGP route received by the third network device from the second network device; and when detecting that the second BGP route set includes a first BGP route but the first BGP route set does not include the first BGP route, determining the first BGP route as an unavailable route.

    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: A first network device includes a processor and a memory having computer readable instructions stored thereon that, when executed by the processor, cause the first network device to obtain a Flow Specification (FlowSpec) rule with redirect indication information. The redirect indication information includes identification information identifying a first virtual private network (VPN) instance configured on a second network device. The indication information also includes instructions for the second network device to redirect data stream matching the FlowSpec rule to the first VPN instance. The first network device is also caused to advertise the FlowSpec rule with the redirect indication information to the second network device.
