课程名称：ISIS路由协议大师课程-阿拉伯版本 概述：本课程旨在帮助学员深入理解ISIS协议，这一协议在服务提供商中广泛应用，并且与MPLS协议和流量工程(TE)密切相关。虽然该课程不包含在CCNA和CCNP企业课程中，但它出现在服务提供商的学习路径中。学员将通过逐步学习来全面掌握ISIS路由协议，即中间系统到中间系统的路由协议。 课程要求：学员需具备对OSPF协议或CCNA课程中的IGP协议的基本了解。 内容简介：IS-IS是一种内部网关协议，旨在网络管理域内使用。与主要用于自治系统之间路由的外部网关协议（如边界网关协议BGP）相比，IS-IS是一种链路状态路由协议，通过稳健地在路由器网络中广播链路状态信息，使每个IS-IS路由器独立构建网络拓扑数据库。与OSPF协议相似，IS-IS使用Dijkstra算法计算最佳路径，并根据计算出的理想路径转发数据包（报文）。 IS-IS协议最初由数字设备公司（Digital Equipment Corporation）开发，作为DECnet第五阶段的一部分。它于1992年由国际标准化组织（ISO）标准化，称为ISO 10589，旨在实现网络设备之间的通信。这一协议的目的在于利用ISO开发的OSI协议栈（CLNS）路由数据报。值得注意的是，IS-IS与互联网工程任务组（IETF）同时开发的OSPF协议具有相似性，后者被扩展以支持在全球互联网的网络层协议（IP）中路由数据报，这一版本被称为集成IS-IS。
This course help you to know ISIS protocol the most used in service provider also most used with MPLS protocol and TE engineering. This course not include in CCNA and CCNP Enterprise course but you find it in service provider track. now you can learn with me step by step to understand well ISIS routing protocol or intermediate system to intermediate system routing protocol # # ## ### ##### ####### ######### ########## ########### ############ ################ ###################### ####################### ############### ######## ############ ############# ############## ################ #############################################################################################################################################################3Requirements of this course know OSPF protocol or IGP protocol in CCNA course #################################################################IS-IS is an interior gateway protocol, designed for use within an administrative domain or network. This is in contrast to exterior gateway protocols, primarily Border Gateway Protocol (BGP), which is used for routing between autonomous systems #########################################################################33IS-IS is a link-state routing protocol, operating by reliably flooding link state information throughout a network of routers. Each IS-IS router independently builds a database of the network's topology, aggregating the flooded network information. Like the OSPF protocol, IS-IS uses Dijkstra's algorithm for computing the best path through the network. Packets (datagrams) are then forwarded, based on the computed ideal path, through the network to the destination#####################################################################################3he IS-IS protocol was developed by a team of people working at Digital Equipment Corporation as part of DECnet Phase V. It was standardized by the ISO in 1992 as ISO 10589 for communication between network devices that are termed Intermediate Systems (as opposed to end systems or hosts) by the ISO. The purpose of IS-IS was to make possible the routing of datagrams using the ISO-developed OSI protocol stack called CLNS.IS-IS was developed at roughly the same time that the Internet Engineering Task Force IETF was developing a similar protocol called OSPF. IS-IS was later extended to support routing of datagrams in the Internet Protocol (IP), the Network Layer protocol of the global Internet. This version of the IS-IS routing protocol was then called Integrated IS-IS
