Abstract: A packet loss processing method and a network device are provided. The method includes: A first node obtains a first forwarding label of a first packet, where the first packet is a discarded packet. The first node determines, based on the first forwarding label, that the first node does not have a LSP corresponding to the first forwarding label. The first node sends a first message to a second node, where the first message includes the first forwarding label, and the first message is used to indicate that the first node does not have the LSP corresponding to the first forwarding label. The second node may be, for example, a peer node of the first node. The first node sends the message to the peer node, to indicate that the first node does not have the LSP corresponding to the forwarding label.

Abstract: A gateway receives a link state packet (LSP) that includes a network identifier of a Layer 2 virtual network and a multicast address and that is sent by each routing bridge (RB) that is on the Transparent Interconnection of Lots of Links (TRILL) network; separately performs calculation on the network identifier and the multicast address that are in each LSP, to obtain a calculation result corresponding to each combination of the network identifier and the multicast address; if the gateway determines that information preconfigured on the gateway matches a calculation result corresponding to a combination of the network identifier and the multicast address, sends a notification message including the network identifier and the multicast address that are in the matched combination to each RB; receives from at least one RB, a multicast packet corresponding to the multicast address in the matched combination, and forwards the multicast packet.
