Abstract
The present invention provides a packet forwarding method and device. The method comprises: a first node receiving a packet for forwarding, wherein a destination address of the packet is a second node; the first node identifying, from topologies generated in advance, a target topology corresponding to the packet, wherein the topologies generated in advance comprise a first topology and a second topology generated according to an MRT algorithm, and a third topology obtained according to an SPF algorithm, wherein the first topology, the second topology and the third topology are different from one another; and the first node identifying, from the target topology, a next hop node for forwarding to the second node, and forwarding the packet to the next hop node. The present invention achieves an object of combining a segmented routing network and an MRT function.
