Abstract

The invention provides an issuing method and device of a multicast forwarding table item. The issuing method comprises the steps of receiving a multicast broadcast, obtaining the corresponding multicast forwarding table item, and judging whether the multicast forwarding table item records an outbound interface or not; judging whether the multicast broadcast is a trans-board forwarding broadcast or not according to a preset rule if there is a record of the outbound interface in the multicast forwarding table item; issuing the multicast forwarding table item to an interface board where the outbound interface exists, an interface board where an inbound interface exists, and a forwarding chip of a main control panel if the multicast broadcast is a trans-board forwarding broadcast; issuing the multicast forwarding table item to a forwarding chip of the interface board where the outbound interface exists if the multicast broadcast is not a trans-board forwarding broadcast. According to the conditions of trans-board forwarding and non-trans-board forwarding broadcasting, the interface board or the forwarding chip of the main control panel irrelevant to the multicast forwarding table item are not used for issuing the multicast forwarding table item, thus waste of the forwarding chip resources are lowered, and forwarding time delay of a frame-type device is also shortened.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a method and device for delivering multicast forwarding entries. Background technique [0002] At present, the multicast technology is usually implemented by using a frame-type device, and each slot of the frame-type device can be inserted with a board (the board includes a main control board and an interface board). Multicast technology is the forwarding of multicast packets through multicast forwarding entries. In order to improve the forwarding efficiency of multicast packets, the multicast forwarding entries are usually sent to the forwarding chip of the board to realize multicast packets. fast forwarding, and the multicast forwarding entry has multiple outbound interfaces. When these outbound interfaces are on one interface board, multicast packets can be forwarded on one interface board, that is, non-cross-board forwarding. When these When the o...
