Abstract: This application describes a multicast packet sending method, apparatus, and system. The method includes a first multicast root node and a second multicast root node belonging to a same VRRP group. The first multicast root node receives a first multicast packet from a specified multicast source, and the second multicast root node receives a second multicast packet from the same specified multicast source, where the first multicast packet and the second multicast packet include same multicast data. The first multicast root node sends the first multicast packet to a first node based on the first multicast root node being a master root node. The second multicast root node discards the second multicast packet based on the second multicast root node being a backup root node. The method reduces waste of a network bandwidth resource.

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.
