Abstract: A communication method includes a first network device obtaining a first route and a second route from a second network device. A first network segment corresponding to the first route is a subnet segment of a second network segment corresponding to the second route. The second route is an aggregated route, and the first route indicates that the first network segment is unreachable. The first network device switches a next hop of the aggregated route based on the first route.

Abstract: A bit index explicit replication (BIER) forwarding entry construction method is provided. The method includes receiving, by a second network device, a first message sent by a first network device, where the first message includes a host routing prefix of the first network device, first BIER information, and second BIER information. The first BIER information includes a bit index forwarding table identifier (BIFT ID) of the first network device, the second BIER information includes a bit forwarding router identifier (BFR ID) of at least one bit forwarding router (BFR) in a first area. The second network device constructs a BIER forwarding entry based on the first BIER information, the second BIER information, and the host routing prefix.

Abstract: A packet transmission method, a transmission control method, an apparatus, and a system are disclosed. A SR path includes a first network node and a second network node. There are a plurality of communication links between the first network node and the second network node. After obtaining a first packet, the first network node determines a first communication link based on a first link quality identifier carried in the first packet, and forwards the first packet to the second network node through the first communication link. The first link quality identifier indicates a first quality requirement on the communication link between the first network node and the second network node. The plurality of communication links between the first network node and the second network node include the first communication link, and link quality of the first communication link meets the first quality requirement.
