Abstract

The embodiment of the invention provides a method for generating routing table items in a distributed router. The method comprises receiving a routing update message including a routing prefix and a first next hop; obtaining a corresponding first routing table item including a second next hop, and adding the first next hop into the first routing table item to generate a second routing table item; starting a delete timer when the priority of the second next hop is lower than that of first next hop information, the duration of the delete timer being a preset time value; and deleting the second next hop in the second routing table item to generate a third routing table item when the time of the delete timer is up, and sending the third routing table item to a forwarding information table of an interface board. The embodiment of the invention also provides a distributed router. Through the technical scheme of the embodiment of the invention, during dual homing networking, packet loss can be effectively avoided when a fault of a main router recovers.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a method for generating routing entries in a distributed router and a distributed router. Background technique [0002] The distributed forwarding router includes a main control board and an interface board. Each interface board has an independent central processing unit (English full name is Central Processing Unit, English abbreviation is CPU) for forwarding processing. The main control board belongs to the control layer of the router. , the main control board generates a routing table item according to the routing information obtained from the routing protocol session interaction, the main control board stores the generated routing table item in the routing table (Routing Table) of the main control board, and sends the routing table item to each interface A forwarding information table (full English name is Forwarding Information Database, ...
