Abstract: Embodiments of this application provide a data transmission method and apparatus. The method includes receiving, by a first device, a data packet, and extracting first address information of the data packet, where the first address information indicates a VNF; retrieving, by the first device based on the first address information, an SRv6 tunnel policy that corresponds to the first address information and that is from a SRv6 tunnel list; obtaining, by the first device, a forwarding path corresponding to a first SRv6 VPN SID, where the forwarding path is used as a data transmission path when the first device communicates with a second device corresponding to the first SRv6 VPN SID; and forwarding, by the first device, the data packet to the VNF based on the forwarding path.

Abstract: A standby routing fault-tolerance unit obtains a plurality of inbound routing packets of a first routing processing unit by using a forwarding unit and an active database unit. The first routing processing unit is a routing processing unit corresponding to an active routing fault-tolerance unit. The standby routing fault-tolerance unit sends the plurality of inbound routing packets of the first routing processing unit to a second routing processing unit. The second routing processing unit is a routing processing unit corresponding to the standby routing fault-tolerance unit.

Abstract: The present disclosure provides a method, an apparatus, and a system for collecting an access control list. A second network device receives a first LSA packet flooded by a first network device, where the first LSA packet includes a first network device identifier and first ACL information, and the first network device and the second network device belong to a same IGP area; and sends an extended first BGP-LS packet to a controller, where the extended first BGP-LS packet includes the first network device identifier and the first ACL information, so that the controller can collect ACL information of the first network device and manage the ACL information of the first network device.

Abstract: The present disclosure relates to the communications field, and discloses a BGP logical topology generation method, and a device. The method includes: obtaining, by a controller, node information of a first forwarder and BGP session information of the first forwarder, and obtaining node information of a second forwarder and BGP session information of the second forwarder; and generating, by the controller, a BGP logical topology between the first forwarder and the second forwarder according to the node information and the BGP session information of the first forwarder, and the node information and the BGP session information of the second forwarder that are obtained. The technical solution provided in the present invention can implement collection of a BGP logical topology between forwarders by the controller, which is favorable for the controller to manage forwarders running the BGP protocol.
