Aggregation and convergence method, device and routing device

Abstract

This specification provides an aggregation convergence method, device and routing equipment, which relate to the technical field of communication. An aggregation convergence method, which is applied to the network processor of the line card board, including: if it is determined that the BFD detection message sent by the connected and peer aggregation member interface is not received within a preset time, then obtain the offline aggregation The BFD session ID of the member interface; generate a BFD event message according to the stored multicast address information and the obtained BFD session ID; send the BFD event message to the switch chip of the line card board, so that the switch chip Aggregate and converge to the processor on this board and the processors on other line cards in the network device respectively according to the BFD session identifier carried in the BFD event message. Through the foregoing method, the aggregation convergence speed of the routing device can be improved.

Description

technical field [0001] This specification relates to the field of communication technologies, and in particular, to an aggregation convergence method, apparatus, and routing device. Background technique [0002] In order to meet the ever-increasing demands of Ethernet link bandwidth and reliability, the application of aggregation ports is becoming more and more extensive, and the number of aggregation member ports is increasing. In a high-performance router, an aggregate port can contain 64 aggregate member ports, which greatly improves the link bandwidth and link reliability of the aggregate port. [0003] Aggregated member ports can be distributed on different line cards and sub-cards. To quickly detect link failures on aggregated member ports and speed up the convergence of aggregated ports, it is necessary to configure 10ms*3 BFD (Bidirectional Forwarding Detection) under the aggregated ports. , Bidirectional Forwarding Detection) session, that is, a BFD packet is excha...

Problems solved by technology

However, when multiple aggregated member ports fail at the same time, for example, a subcard with 10 aggregated member ports is removed, the processor of this board needs to analyze BFD event packets, eliminate the faulty aggregated member ports one by one to achieve convergence, and After the convergence is completed, other line cards in the network device are notified to perform convergence. The time consumed by this process will undoubtedly be prolonged due to the increase in the number of aggregation member ports that fail at the same time, resulting in a slowdown in the convergence time.
