课程名称：网络路由基础 概述：本课程为期13小时，深入探讨学习动态路由协议所需的所有路由基础知识。这是希望在路由领域建立扎实基础的学习者所需掌握的基本内容。课程将详细涵盖以下几个方面：路由的简要历史及其背后的“为什么”；将路由问题细分为子问题；IP地址和子网划分；路由在TCP/IP分层中的定位；地址解析协议（ARP）背后的原因；路由中的下一跳概念；路由表（RIP或路由信息库）；控制平面与数据平面的详细比较；第二层多播（为什么路由协议使用多播地址）；虚拟路由和转发（VRF）的概念及其必要性；静态路由的下一跳和出口接口配置；代理ARP的概念；管理距离（AD）的概念；静态路由故障排除；长前缀与管理距离的比较；负载平衡及浮动路由概念；距离矢量路由与链路状态路由的对比；避免环路的分割视天（Split Horizon）技术；以及对OSPF的简要介绍及必要步骤。 课程首先将从路由的简要历史与其必要性入手。路由的概念自计算机网络早期便已存在。20世纪60年代，麻省理工学院（MIT）的研究人员开发了首个计算机网络，用于连接计算机并共享存储和处理能力。随着网络规模和复杂度的增加，需求更加高效、可靠的路由。而在70年代，施乐公司开发了名为互联网协议（IP）的路由协议，用于在网络之间路由数据包。80年代，因特网工程任务组（IETF）成立，以标准化互联网协议和技术，包括路由，IETF制定了边界网关协议（BGP），该协议至今仍在互联网中用于交换路由信息。90年代，万维网的崛起和个人电脑及其他联网设备的大量普及导致了互联网流量的急剧增长，这促使开发出新的路由协议和技术以满足需求。如今，路由已成为现代计算机网络和互联网的重要组成部分，并随着新技术和协议的发展而不断演变。
This is a 13 hours course which talks about all the routing fundamentals you need to learn dynamic routing protocols. At least this much you should know if you wish to have a solid base in routing. Following are covered in great details.A brief history of routing and "Why" behind routing.Let's divide the routing problem in to sub-problems.IP Addressing and SubnettingWhere routing fits in TCP/IP layering.Why behind Address Resolution Protocol (ARP)Concept of Next-Hop in RoutingWhat is Routing Table (RIP or Routing Information Base)Control Plane vs Data Plane in DetailLayer-2 Multicast (Why routing protocol use multicast addresses)What and Why behind Virtual Routing and Forwarding (VRF's)Static routing with next hop and Static routing with exit interface.Static routing with next hop and exit interfaceConcept of Proxy ARPConcept of Administrative Distance (AD)Troubleshooting Static RoutingLonger Prefixes vs Administrative DistanceLoad Balancing and concept of Floating RoutesDistance Vector Routing Vs Link State RoutingWhy Split Horizon (Loop Avoidance using Split-Horizon)Brief introduction about OSPFSteps necessary for OSPFAs understanding of routing fundamentals is mandatory, let's start it with the brief history and why it is required. The concept of routing has been around since the early days of computer networking. In the 1960s, researchers at the Massachusetts Institute of Technology (MIT) developed the first computer networks, which were used to connect computers and share resources such as storage and processing power. As networks grew in size and complexity, the need for more efficient and reliable routing became apparent. In the 1970s, researchers at Xerox Corporation developed the Xerox Network System (XNS), which used a routing protocol called the Internet Protocol (IP) to route data packets between networks. In the 1980s, the Internet Engineering Task Force (IETF) was formed to standardize internet protocols and technologies, including routing. The IETF developed the Border Gateway Protocol (BGP), which is still used today to exchange routing information between networks on the internet. In the 1990s, the rise of the World Wide Web and the proliferation of personal computers and other devices connected to the internet led to a tremendous growth in internet traffic. This led to the development of new routing protocols and technologies to handle the increased demand. Today, routing is a critical part of modern computer networks and the internet, and it continues to evolve as new technologies and protocols are developed.
