如何在网络中实现VLSM和路由汇总

How to Realize VLSM and Route Summarization in the Internet

在大型网络设计中使用VLSM和路由汇总可以有效减少IP地址的浪费,减小路由选择表,提高网络性能。本文通过对分类网络和无类网络路由选择的原理、实现和对比,来阐述如何在网络中实现VLSM和路由汇总。

Using VLSM （Variable - Length Subnet Mask） and Route Summarization in the large - sized network designing can effectively decrease the waste in IP addresses, reduce the routing table and enhance the network performance. This essay, on the analysis of the principles, the realization and the contrast of classified network and unclassified network, elaborates how to achieve VLSM and Route Summarization.
