Abstract

Embodiments of the present invention provide a PBR-based multiple next-hop load sharing method and device. In the embodiment of the present invention, PBR has been configured on the interface of the routing device, and the method includes: traversing the PBR configured on the interface; if the PBR includes multiple next hops, and the multiple next hops are configured as load In sharing mode, an IP prefix is ​​assigned to the multiple next hops; based on the IP prefixes, multiple equivalent routes corresponding to the next hops are generated. In this way, load sharing between multiple next hops is realized. This automatic configuration method can effectively improve configuration efficiency and ensure correct configuration.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a PBR-based multiple next-hop load sharing method and device. Background technique [0002] Policy based routing (PBR) is a mechanism for identifying and forwarding packets according to policies configured by users. This mechanism is different from ordinary routing table forwarding (forwarding according to the destination address table lookup), which can identify packets according to the matching characteristics configured by users, and send the packets matching the characteristics to the specified next hop. [0003] When there are multiple next hops, the multiple next hops are usually manually configured as equal-cost routes, and then the IP prefix corresponding to the equal-cost routes is referenced under PBR to implement load balancing among multiple next hops. [0004] However, manually configuring equal-cost routes is not efficient, and it is prone to errors w...
