RIP协议的基本配置(1)
本实验对RIP协议进行基本的配置,涉及到配置RIP协议所必须的命令和常用的监测命令。 1.实验目的 通过本实验,读者可以掌握以下技能: 在路由器上启动RIP协议; 声明相应网络进入RIP路由进程; 查看路由表并理解相关字段含义; 查看RIP协议配置信息; 监测RIP协议相关信息。 2.设备需求 本实验需要以下设备: Cisco路由器3台,分别命名为R1、R2和R3,均要求具有1个以太网接口和2个串行接□; 3条DCE电缆和3条DTE电缆,或3条DCE转DTE电缆; 1台终端服务器,如Cisco 2509路由器。及用于反向Telnet的相应电缆; 1台带有超级终端程序的PC机,以及Console电缆及转接器。 3.拓扑结构及配置说明 本实验拓扑结构如图5.1所示,首先把DCE电缆和DTE电缆进行对接,共组成3对电缆。然后用这3对电缆把R1和R2"RE和R3、R2和R3分别连接起来。各路由器使用的接口及其编号见图5.1中的标注。 IP地址分配如下: R1: E0 172.16.1.1, 50 172.16.12.1, 51 172.16.13.1; R2: E0 172.16.2.2, 50 172.16.12.2, 51 172.16.23.2; R3: E0 172.16.3.3, 50 172.16.13.3, 51 172.16.23.30 子网掩码均为 255.255.255.00 ![]() 实验中R、R2之间和R、R3之间的串行线路速率设置为5OOkbit/s;R2、R3之间的串行线路速率设置为64kbit/s。 本实验要求通过对RIP路由选择协议的配置,实现全网的连通。 4.实验配置及监测结果 实验环境准备就绪后,打开PC机、访问服务器和路由器的电源。开始进行实验。 现在假设我们不知道各路由器串行接口所连接的电缆是DCE电缆还是DTE电缆,同时路由器的E0接口均没有连接任何设备。在这样的基础上开始配置3台路由器,并启动RIP路由选择协议。 具体配置过程如配置清单5-1、5-2所示,配置清单后有详细的讲解。 配置清单5-1配置以太网接口和串行接口 第1段:配置R1网络接口 R1# R1#show controllers serial 0 HD unit 0, idb = 0x95659C, driver stmcture at 0x95C910 buffer size 1524 HD unit 0, V.35 DCE cable cpb = 0xE2, eda = 0x2904, cda = 0x2918 RX ring with 16 entries at OxE22800 00 bd_ptr==0x2800 pak=0x95DB94 ds=0xE25A4C status==80 pak_size=22 01 bd_ptr=0x2814 pak=0x960328 ds=0xE2CCC8 status=80 pak_size=22 ...(类似内容,省略多行) 0 missed datagrams, 0 overruns 0 bad datagram encapsulations, 0 memory errors 0 transmitter underruns 0 residual bit errors R1#sh controllers ser 1 HD unit 1, idb = 0x961614, driver structure at 0x967988 buffer size 1524 HD unit 1, cpb = 0xE3, eda = 0x850, cda = 0x864 RX ring with 16 entries at OxE30800 00 bd_ptr=0x0800 pak=Ox9690B4 ds==OxE34E80 status=80 pak_size=22 ...(类似内容,省略多行) 01 bd__ptr=0xl014 pak=0x000000 ds=0xE22EA4 status=80 pak_size=22 0 missed datagrams, 0 overruns 0 bad datagram encapsulations, 0 memory errors 0 transmitter underruns 0 residual bit errors R1#conft Enter configuration commands, one per line.
