Abstract

The present disclosure relates to a message forwarding method and device. This method is used for a specified first PE device, including: obtaining sub-AC information of a second PE device across the L2VPN network; wherein, the sub-AC is an aggregated interface connecting a PE device to the same CE device, and the sub-AC information includes a sub-AC ID and a sub-AC AC state; according to the sub-AC information of the first PE device and the sub-AC information of the second PE device, configure the matching relationship between the sub-AC of the first PE device and the sub-AC of the second PE device; generate a The matching information of the matching relationship between the sub-AC and the sub-AC of the second PE device, and sending the matching information to the second PE device. The designated PE device can automatically configure the matching relationship between the local sub-AC and the remote sub-AC, so that after a link failure in the aggregated link, the designated PE device can automatically update the local sub-AC and the remote sub-AC The matching relationship among them saves physical link resources and effectively improves link reliability.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a message forwarding method and device. Background technique [0002] In related technologies, Ethernet link aggregation is to aggregate multiple physical interfaces together to form a logical dynamic aggregation group, and the upper-layer entity using the link aggregation service regards multiple physical links in the same dynamic aggregation group as one logical link. figure 1 A schematic diagram showing Ethernet link aggregation in the related art. like figure 1 As shown, device A and device B are connected through three physical links, and the three physical links form a logical link. The bandwidth of the logical link can reach the sum of the bandwidths of the three physical links at most, so as to achieve the purpose of increasing link bandwidth. In addition, the three physical links in the logical link can dynamically back up each other. When one o...
