最近在帮朋友做网络，正好顺便复习一下Cisco方面的知识，呵呵，人都说知识的海洋需要点滴的积累，我就打算做个Cisco点滴博文系列，(*^__^*) 嘻，不知道能坚持多久，不过，我想，重在参与，贵在坚持~~
过段时间我把以前和现在的这些网络小项目整合起来，制作成项目案例发布出来，希望对大家，尤其是刚开始学习Cisco的朋友们能够有所帮助，也希望高手们能够为我指点迷津，让我们相互学习，相互进步吧~~(*^__^*) 呵呵，废话不多数了，开始了~~
我的实验环境是小凡+SecureCRT
现在我们说一下关于RIP协议的简单介绍，哈~~复习笔记记录~~
RIP属于一种动态路由协议，动态路由协议包括距离向量路由协议和链路状态路由协议。RIP（Routing Information Protocols，路由信息协议）是使用最广泛的距离向量路由协议。RIP是为小型网络环境设计的，因为这类协议的路由学习及路由更新将产生较大的流量，占用过多的带宽。每个有RIP功能的路由器默认情况下每隔30秒利用UDP 520端口向与它直连的网络邻居广播（RIP v1）或组播（RIP v2）路由更新。因此路由器不知道网络的全局情况，如果路由更新在网络上传播慢， 将会导致网络收敛较慢， 造成路由环路。 为了避免路由环路，RIP采用水平分割、毒性逆转、定义最大跳数、闪式更新、抑制计时5个机制来避免路由环路。
其实配置RIP网络很简单，我们先来看看如何配置RIPv1吧~~
拓扑图如下：
连线如图：
Router1 S0/0 <----> Router2 S0/0
Router2 S0/1 <----> Router3 S0/1
Router3 S0/0 <----> Router4 S0/0
Router1 F1/0 <----> VPCS V0/1
Router4 F1/0 <----> VPCS V0/2
R1配置
R1(config)#router rip //启动RIP进程

R1(config-router)#network 1.1.1.0 //通告网络

配置接口IP地址：
R1(config)#int f1/0
R1(config-if)#ip add 1.1.1.1 255.255.255.0

R1(config-if)#exit

R1(config-if)#ip add 10.0.0.1 255.255.255.0
R1(config-if)#no shut
R1(config-if)#exit
R1#show ip route //该命令用来查看路由表
