A method and device for learning a vpls network mac address

Abstract

Embodiments of the present invention provide a method and device for learning a VPLS network MAC address, which relate to the field of data communication, and can realize that when learning a source MAC address of a VPLS message, it is only necessary to query the MAC address forwarding table items learned by the same ingress path without searching All MAC address forwarding entries stored in the VPLS broadcast domain include: creating a source MAC address information management table for each ingress path of the device; Searching for a matching source MAC address information management entry in the table, if not found, adding a new source MAC address information management entry in the corresponding source MAC address information management table and saving the source MAC address. The invention reduces the search range of the MAC address forwarding table items, thereby improving the learning efficiency of the source MAC address, and further improving the forwarding efficiency of the VPLS message.

Description

technical field [0001] The invention belongs to the field of data communication, and in particular relates to a method and device for learning a MAC address in a VPLS network. Background technique [0002] VPLS (Virtual Private LAN Service, Virtual Private LAN Service) is a kind of Metro Ethernet technology, which can effectively connect each access point, and realize point-to-point, point-to-multipoint, Multipoint-to-multipoint Ethernet services. From the point of view of the connection mode, VPLS provides users with a simulated LAN connection by using the wide-area backbone network of IP (Internet Protocol, a protocol for interconnecting networks) / MPLS (Multi-Protocol Label Switching, multi-protocol label switching) . From the point of view of service provision, the LAN simulated by VPLS provides convenient and flexible Ethernet services, and this simulated LAN connection is transparent to each user branch LAN across the WAN, and each branch LAN seems to be connected to ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method and device for learning a VPLS network MAC address, which is used to solve the problem that in the prior art, source MAC address learning actually only needs to search for MAC address forwarding entries created based on the source MAC addresses of messages received on the same ingress path. , but it is necessary to search for all MAC address forwarding entries in the entire VPLS broadcast domain, the search efficiency is low, and the problem of affecting the efficiency of VPLS packet forwarding
