Abstract: This application discloses a routing loop reduction method, an apparatus, and a system. The method includes: a first network device receives a first packet, the first packet carries identifier information and a first route, and the identifier information includes a source device identifier of a device that advertises the first route or a source protocol identifier of a routing protocol to which the first route belongs. The first network device runs a first routing protocol and a second routing protocol, and the first routing protocol is different from the second routing protocol. The first network device determines, based on the identifier information, that advertising the first route to a second network device running the second routing protocol causes a routing loop.

Abstract: Embodiments of this application disclose a route advertisement method and a route generation method, to improve route convergence efficiency and reduce a packet loss rate. The route advertisement method includes: A first network device obtains routing information of a destination device. The first network device generates a first route advertisement message, where the first route advertisement message includes the routing information of the destination device, a routing prefix, and first indication information. The first network device sends the first route advertisement message to a second network device. The first route advertisement message is used to indicate the second network device to generate a route to the destination device based on the routing information of the destination device. The first indication information is used to indicate the second network device to iterate, to a route corresponding to the routing prefix, the route to the destination device.

Abstract: This application provides a method and an apparatus for sending a multicast packet. In the method, an ingress device obtains a region identifier of a region corresponding to a received multicast packet. The ingress device obtains, based on the region identifier and a forwarding entry, an address of an intermediate device that is used to forward the multicast packet to the region. The forwarding entry includes the region identifier and the address of the intermediate device. The ingress device sends the multicast packet based on the address of the intermediate device. An intermediate device obtains, based on a multicast packet from an ingress device, a region identifier of a region corresponding to the multicast packet. The intermediate device obtains an address of a next-hop device based on the region identifier and a forwarding entry. The intermediate device sends the multicast packet based on the address of the next-hop device.

Abstract: The application provides a method: for any network node in a network, the network node may collect a traffic count result of traffic from the network node to a destination network node that belongs to a same area as the network node. Because destination network nodes of the network node are used to indicate an egress node on a path for forwarding a packet by the network node in the area, a control node may learn of, based on count results corresponding to the destination network nodes, traffic transmitted from the network node to egress nodes. This facilitates the control node to determine a traffic distribution feature in the network. The application provides a method that network nodes collect local aggregated traffic statuses, and then the control node determines the traffic distribution feature in the network based on the local aggregated traffic statuses collected by the network nodes.
