Problems solved by technology

[0004] From the format of these two commands, each command needs to specify the IP address and subnet mask. Obviously, this kind of configuration command requires the staff to be very familiar with the network topology, and requires professional knowledge of routing aggregation to correctly configure and effective Aggregation routing; on the other hand, the existing command configuration is too cumbersome. When there are many subnets, it is necessary to configure a lot of aggregation commands to achieve the effect. In a large network environment, such configuration is particularly complicated, which greatly consumes the work of personnel. time, in this article we call such aggregation as manual aggregation

Embodiment Construction

[0028] Fig. 1 is a flow chart of a route aggregation method according to an embodiment of the present invention. As shown in FIG. 1 , the route summarization method includes the following steps: S102, configuring a route summarization command; S104, summarizing intra-domain routes or external routes of routers according to the route summarization command.

[0029] Among them, there are two ways of route summarization: route summarization with specified subnet mask length and automatic route summarization.

[0030] In route summarization with specified subnet mask length, the user needs to specify the subnet mask length. When inter-area LSAs or external LSAs are generated, they are aggregated according to the specified mask length. Among them, multiple subnet mask lengths can be specified for aggregation. At this time, the aggregation priority decreases from the largest to the smallest subnet mask length, that is, the larger the subnet mask, the higher the priority. Amo...

Abstract

The invention discloses a route assembling method and a system, wherein the route assembling method comprises the following steps: allocating route assembling order, and assembling intra-area route or external route of a router according to route assembling order. The invention can save resource consumption of route equipment and can improve operating efficiency of route equipment.

Description

technical field [0001] The present invention relates to the field of communication, and more particularly relates to a route aggregation method and system. Background technique [0002] Open Shortest Path First Routing Protocol (OSPF) is a dynamic routing protocol based on link state. In this protocol, when there are too many routing entries to be advertised, the advertised routes can be aggregated into some routing entries with shorter subnet masks by configuring area range and route summary. , so as to achieve the purpose of reducing the number of routes, thereby reducing the size of the routing table, saving routing device resources, and making routers and other devices run more efficiently. [0003] In the existing OSPF protocol implementations of various manufacturers, these two methods are through area<area_id>range <ipaddr> <mask>or summary <ipaddr> <mask>These two commands are implemented, area range is mainly to summarize the netwo...
