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.

Abstract

The invention provides an aggregation convergence method and device and routing equipment, and relates to the technical field of communication. The aggregation convergence method is applied to a network processor of a line card board, and comprises the following steps: if it is determined that a BFD detection message sent by a connected aggregation member port at an opposite end is not received within a preset time, obtaining a BFD session identifier of an offline aggregation member port; generating a BFD event message according to the stored multicast address information and the acquired BFD session identifier; and sending the BFD event message to a switching chip of the line card board, so that the switching chip performs aggregation convergence on a processor of the line card board and processors on other line card boards in the network equipment according to the multicast address information and the BFD session identifier carried by the BFD event message. Through the method, the aggregation convergence speed of the routing equipment can be improved.

Description

technical field [0001] This specification relates to the technical field of communications, and in particular to an aggregation convergence method, device, and routing device. Background technique [0002] In order to meet the increasing requirements of bandwidth and reliability of Ethernet links, aggregation ports are more and more widely used, and the number of aggregation member ports is increasing. In high-performance routers, the aggregation port can contain 64 aggregation member ports, which greatly improves the link bandwidth and link reliability of the aggregation port. [0003] Aggregation member interfaces can be distributed on different line cards and subcards. In order to quickly detect link failures of aggregation member interfaces and speed up aggregation interface convergence, it is necessary to configure 10ms*3 BFD (bidirectional forwarding detection) on the aggregation interface. , Bidirectional Forwarding Detection) session, that is, a BFD packet is exchan...
