Problems solved by technology

[0007] It can be seen from the above that according to the existing technology, the downlink line card is inefficient when learning the MAC address of multicast packets, and the more ACs and PWs the downlink line card contains, the more the number of the same interface messages will be. Learning modules are more stressful

Embodiment Construction

[0038] This embodiment provides a distributed device multicast message MAC address learning method, using the following scheme:

[0039] Select one of the multicast members of the multicast message to learn the source MAC address, and other multicast members directly forward the message.

[0040] Further, randomly select one of the multicast members to learn the MAC address, or,

[0041] Select a multicast member with a fixed member number for MAC address learning.

[0042] In the present invention, the learning flag in the message is set in the uplink line card of the distributed device according to the configuration of the user, so as to mark whether the message needs to learn the MAC address.

[0043] Further, if the member is selected to learn the MAC address, the original learning flag of the member is not modified; if the member is not selected, the learning flag of the member is set to be disabled, so as to mark that the message does not need to be learned.

Abstract

The invention discloses a method and device for learning a multicast message medium access control address of a distributed device. For a multicast message in a downlink line card in a distributed device, only one of a plurality of members of the multicast message is selected for source MAC address learning. By adopting the invention, the MAC learning interface messages generated by the multicast members of the distributed equipment on the downlink line cards can be reduced, and the MAC address learning efficiency can be improved.

Description

technical field [0001] The invention relates to the switching technology of distributed two-layer forwarding equipment, in particular to a method and device for learning a medium access control address of a distributed equipment multicast message. Background technique [0002] A device with a distributed architecture includes multiple line cards, and packets need to pass through the uplink and downlink line cards respectively before they can be correctly forwarded. The structure of distributed equipment is as follows figure 1 As shown, it includes uplink line cards, downlink line cards, and switching units. L2VPN (Layer 2 Virtual Private Network, Layer 2 Virtual Private Network) VPLS (Virtual Private LAN Service, Virtual Private LAN Service) service implemented by distributed equipment, usually completes the destination MAC (Media Access Control, Media Access Control) address on the uplink line card Lookup, complete source MAC address learning on the downlink line card.
