摘要
扩展访问控制列表因其具有配置灵活、精确控制的特点,越来越成为网络上控制数据流量的一种重要技术。应用Packet Tracer仿真软件,设计了模拟拓扑图,给出了路由器和三层交换机的接口设置、IP地址分配以及配置命令,对使用扩展访问控制列表前后的结果进行了测试和对比分析,并在实际的网络设备上进行了实验验证。
Because of its characters such as flexible configuration and precise control,extended ACL is becoming an important technology to control network traffic.Based on Packet Tracer,the simulation topological diagram is designed,ports of routers and third-layer-switch are set and IP addresses are distributed.The configuration commands of routers and third-layer-switch are analyzed respectively.Thus,the simulation test for extended ACL among Cisco routers associated with third-layer-switch is carried out,comparing the differences between two results before and after application of extended ACL.And the experimental test in the real network prove the design of the virtual network feasible.
