本课程名为“路由器路由过滤实践”，旨在教授学员如何使用前缀列表（Prefix-list）来过滤路由表中的非预期路由。此技能有助于保持组织内部路由表的整洁，从而保护网络免受恶意注入网络的侵害。 **课程内容总结：** 1. **建立拓扑结构：** 构建一个模拟三台路由器之间路由的实验环境。 2. **网络类别识别：** 讲解网络类别，演示如何使用子网掩码来识别网络。 3. **四种过滤场景：** 分步演示四种使用前缀列表过滤路由的实际案例。 * **案例一：** 过滤特定源地址和掩码的网络。 * **案例二：** 允许未经过子网划分的A类网络。 * **案例三：** 允许未经过子网划分的B类网络。 * **案例四：** 允许未经过子网划分的C类网络。 讲师将逐步搭建实验环境，鼓励学员在自己的模拟器上跟随操作。本课程具有高度实践性，适合所有能够操作路由器并遵循课程步骤的学习者。 **最终讲座总结：** 课程最后会总结路由过滤的重要性，探讨路由过滤的目的、实现机制、最佳实践以及针对不同协议的特殊考量。 欢迎大家参加本课程，开始学习！
In this course the student will learn important skill of how to use Prefix-list and filter unwanted routes from the routing tables. This skill will also help the student to keep the routing tables clean in an organization, thus keeping the network safe from malicious injected networks.Follow the author as he goes through the steps below1. Building Topology to simulate a routing between three routers. 2. The instructor will go through the classes of networks which will show how to identify networks using subnet mask. 3. Four cases are created that will show step by step filtering of the routes using Prefix-lists. 4. Case 1 will have a scenario of filtering a network using source address and mask. 5. Case 2 will have a scenario of allowing routes that are class A but not subnetted. 6. Case 3 will have a scenario of allowing routes that are class B but not subnetted. 7. Case 4 will have a scenario of allowing routes that are class C but no subnetted. The instructor is going to build the lab step by step and wishes to have the students to mimic the lab in their own simulator and follow the steps as the network is built. The course is practical in nature and is suitable for anyone who has access to routers and can follow the steps in this course. The last lecture summarizes the importance of route filtering. The instructor discusses the purpose of route filtering, mechanisms for route filtering, best practices, protocol specific considerations. Welcome to the course and lets start learning.
