    Abstract: A method includes a first provider edge (PE) device sending, to a second PE device, a media access control (MAC) route learned from a customer edge (CE) device and a virtual local area network (VLAN) identifier, wherein the second PE device generates a MAC forwarding entry based on the MAC route and the VLAN identifier, where the MAC forwarding entry is used to directly forward, using the CE device, a packet whose destination MAC address is the CE device or a MAC address of a terminal device accessing the CE device. An outbound interface identifier included in the MAC forwarding entry is an identifier of an interface connected to the CE 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.

    Abstract: A route processing method is implemented by a first PE device and includes receiving a VPN route that includes a second SRv6 VPN SID and a third SRv6 VPN SID from a second PE device; determining that the second SRv6 VPN SID is the same as a first SRv6 VPN SID; and establishing a second path based on the third SRv6 VPN SID, where when a first path directly connected to the first PE device and the second CE device is faulty, the second path is used by the first PE device to forward a packet to the second CE device.

    Abstract: The method includes the following steps: The second PE device sends, to the first PE device, a MAC route learned from the CE device. The first PE device generates a MAC forwarding entry based on the MAC route. The first PE device may forward, based on the MAC forwarding entry by using the CE device, a packet whose destination MAC address is the CE device or a MAC address of a terminal device accessing the CE device. An outbound interface identifier included in the MAC forwarding entry is an identifier of an interface connected to the CE device. According to the method in this application, load can be effectively shared between the second PE device and the first PE device, and system bandwidth resources can be properly used.

    Abstract: This application relates to the field of computer network technologies and discloses an autonomous system (AS) pair verification method, apparatus, and device. The method can avoid incorrect determining of an AS pair in path information of an AS path during verification of the AS path, and improve accuracy of verifying the AS path. The method is applied to a network device. The method includes: obtaining path information including an AS pair; determining region information of a region to which the AS pair in the path information belongs; and verifying the AS pair based on the determined region information of the region to which the AS pair belongs, where the AS pair in the path information includes two adjacent AS numbers in the path information.

    Abstract: A packet processing method includes a second device that sends a first packet to a first device, where the first packet includes a first segment routing header (SRH). After receiving the first packet, the first device determines whether the first packet includes a first segment identifier. When the first packet includes the first segment identifier, the first device deletes the first SRH, performs an encapsulation operation to generate a second packet, and forwards the second packet. That is, when a function or an indication corresponding to the first segment identifier is to perform the encapsulation operation, after receiving the first packet, the first device may delete the first SRH in the first packet based on an actual case, and perform the encapsulation operation to generate the second packet, where the second packet does not include the first SRH.

    Abstract: This application discloses a route advertisement method, a packet forwarding method, a device, and a system. A first network device obtains a first VPN route and a second VPN route that have a same route prefix and a same route distinguisher but different VPN identifiers and different next hops. The first network device allocates a third VPN identifier to the first VPN route and the second VPN route, and stores, on a forwarding plane, a first correspondence between the third VPN identifier and a first VPN identifier that is included in the first VPN route and a second correspondence between the third VPN identifier and a second VPN identifier that is included in the second VPN route. The first VPN route and the second VPN route that belong to a same VPN can form fast reroute or load balancing.
