摘要： Embodiments of the present invention provide 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 Interior Gateway Protocol IGP area; and sends an extended first BGP-LS packet to the 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. By using the method, ACL information of any one or more network devices in the IGP area can be collected and managed. In this way, a method for collecting and managing ACL information is provided, and ACL information maintenance work is simplified.

摘要： The present invention discloses a packet forwarding method, including: determining, by an ingress provider edge Ingress PE in an Ethernet virtual private network instance EVI, that a state of the EVI on a first egress Egress PE is active Active, where an Ethernet virtual private network EVPN corresponding to the EVI includes a first CE; determining, by the Ingress PE, that a state of the EVI on a second Egress PE is inactive Inactive; skipping, by the Ingress PE, forwarding a broadcast, unknown unicast, or multicast BUM packet to the second Egress PE, where the BUM packet is from the first CE; and forwarding, by the Ingress PE, the BUM packet to the first Egress PE. Repeated BUM traffic that is transmitted in a bearer network and is not finally sent to a remote site is reduced; therefore, a waste of bandwidth in the bearer network is reduced.

摘要： The present application discloses a method, a device and a system for establishing an LSP. The method includes: allocating, by a proxy node device, a label for a destination node device, generating a label mapping message carrying the label, an address of the destination node device and an address of the proxy node device, and sending the label mapping message to an upstream node device to initiate establishment of a first LSP from an entry node device to the proxy node device; stitching, by the proxy node device, the first LSP with a second LSP to form a third LSP from the entry node device to the destination node device, where the second LSP is an LSP established between the proxy node device and the destination node device. According to technical solutions in embodiments of the present invention, there is no need for the entry node device and the intermediate node device to pre-configure a static route reaching the destination node device, which solves problems of complicated configuration as well as difficult management and maintenance due to a need to configure the static route when LSPs of different protocols are stitched in the prior art.

摘要： Embodiments of the present invention provide a traffic switching method and apparatus. The method includes: establishing a mapping relationship between a performance parameter of a network and a forwarding node switching sequence, where the performance parameter of the network includes link usage before switching and link usage after switching; when traffic switching needs to be performed, obtaining a current performance parameter of the network, and determining, according to the mapping relationship, a switching sequence corresponding to the current performance parameter; and delivering a switching instruction to forwarding nodes according to the switching sequence, so as to control the forwarding nodes to sequentially perform traffic switching. In this way, traffic switching can be systematically implemented, thereby effectively avoiding a link congestion phenomenon in a switching process, and ensuring network performance.
