Abstract: A method for forwarding a packet in a network. The network includes a first network node, a second network node, and a third network node. The method is applied to the first network node, and the method includes: generating a correspondence between a first segment identifier (SID) and a second SID, where the first SID is an identifier that corresponds to the private network, and the second SID is an SID of the third network node; receiving a first packet whose destination address is the first SID; and when it is determined that the second network node is unreachable, pushing the second SID into the first packet to generate a packet, and sending the packet to the third network node.

Abstract: Embodiments of this application disclose a packet sending method, a device, and a system, so that a specified network device does not use a backup forwarding path to forward a packet, thereby reducing, to some extent, a technical problem such as network resource waste or network congestion caused by a loop problem. The method includes: A first network device obtains a first packet destined for a destination device; the first network device adds a first indication identifier to the first packet to generate a second packet, where the first indication identifier is used to indicate a second network device to avoid using a backup forwarding path from the second network device to the destination device to send the second packet to the destination device; and the first network device sends the second packet to the second network device by using a first forwarding path.

Abstract: This application discloses a forwarding entry generation method, a packet sending method, a network device, and a system, so that a specified network device cannot use a backup forwarding path to forward a packet, thereby reducing, to some extent, a technical problem such as network resource waste or network congestion caused by a loop problem. The method includes: A first network device obtains routing information advertised by a second network device; and the first network device determines that the routing information advertised by the second network device matches a summary route stored in the first network device, and generates, based on a segment identifier of the second network device, a forwarding entry corresponding to the summary route. The forwarding entry includes the segment identifier of the second network device, and a forwarding path corresponding to the forwarding entry passes through the second network device.
