实验七:动态态路由协议的配置

这个和实验六静态路由协议的配置差不很多:总结上次的经验,这次把每一步的步骤和代码详细跟着,上次为啦贪图方便,就把代码一股脑的全放上面拉,今天同学问我实验代码,我也是第一次推销我的博客,为了方便看,这次特意写的详细一点:
首先我先介绍一下与静态路由协议的配置的不同之处。

由手动添加路由表信息即静态路由协议配置如下:

pc1~px3切换到全局模式下,ip  route  172.16.3.0   255.255.255.0   172.16.2.2

                                                   第一个是目的网路号,第二个是目的网路号对应的子网掩码,第三个是到目的网路的下一跳端口。

show    ip  route

pc3~pc1

ip route 172.16.1.0 255.255.255.0 172.16.2.1 

show ip route

而现在动态路由协议的配置如下:

在全局配置模式下:

R1:

route  rip

network 172.16.1.0 网络号

network 172.16.2.0

退出

show ip route


R2:

route  rip

network 172.16.2.0 网络号

network 172.16.3.0

退出

show ip route

具体配置如下:

(一)先在下图上设置网络拓扑图如下:



选用路由器是选R3620,1sot  选一个因特网口和一个串口的,路由器R1,R2

选取交换机S2950,交换机s1,s2

R1~R2 串口serial0/0 指定数据通信端DCE,R,serial0/0

R1 0/1~s1 0/1.....R2 0/1~S2 0/1

最后添加路由表,r1和r2互通,p1,p2,p3设置好网关,

一共有三个网络,上图已标记清楚,

二;在下图上设置如下:


(1)首先设置好路由器,让路由器R1和R2可以相通。并测试

R1: enable

       configure terminal

       hostname R1

        interface serial 0/0

        ip  address 172.16.2.1 255.255.255.0

       clock rate 64000          DCE端

      no  shutdown

r1Router>Router>Router>enableRouter#configure terminalEnter configuration commands, one per line.  End with CNTL/Z.Router(config)#hostname R1R1(config)#interface serial 0/0R1(config-if)#ip address 172.16.2.1 255.255.255.0R1(config-if)#clock rate 64000R1(config-if)#no shutdown%LINK-3-UPDOWN: Interface Serial0/0, changed state to up%LINK-3-UPDOWN: Interface Serial0/0, changed state to down%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to down%LINK-3-UPDOWN: Interface Serial0/0, changed state to up%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to upR1(config-if)#endR1#


R2:

      configure terminal

       hostname R1

        interface serial 0/0

        ip  address 172.16.2.2 255.255.255.0

             DP端

      no  shutdown


Router>Router>Router>enableRouter#configure terminalEnter configuration commands, one per line.  End with CNTL/Z.Router(config)#hostname R2R2(config)#interface serial 0/0R2(config-if)#no shutdown%LINK-3-UPDOWN: Interface Serial0/0, changed state to upR2(config-if)#ip address 172.16.2.2  255.255.255.0R2(config-if)#exitR2(config)#exitR2#

并测试R1和R2是否可以通信:ping 172.16.2.1

R2#ping 172.16.2.1Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 172.16.2.1, timeout is 2 seconds:!!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 msR2#R2#

(2)设置网关并测试

 R1

enable

configure terminal

interface ehternet 0/0以太网端口

ip  address 172.16.1.1 255.255.255.0

no shutdown

路由器R2设置如上:

测试pc1到R1左端能否通信:

C:>ping 172.16.1.1Pinging 172.16.1.1 with 32 bytes of data:Reply from 172.16.1.1: bytes=32 time=60ms TTL=241Reply from 172.16.1.1: bytes=32 time=60ms TTL=241Reply from 172.16.1.1: bytes=32 time=60ms TTL=241Reply from 172.16.1.1: bytes=32 time=60ms TTL=241Reply from 172.16.1.1: bytes=32 time=60ms TTL=241Ping statistics for 172.16.1.1:     Packets: Sent = 5, Received = 5, Lost = 0 (0% loss),Approximate round trip times in milli-seconds:     Minimum = 50ms, Maximum =  60ms, Average =  55msC:>C:>

测试pc3到R2左端

C:>ipconfig /ip 172.16.3.2 255.255.255.0C:>ipconfig /dg 172.16.3.1C:>ping 172.16.3.1Pinging 172.16.3.1 with 32 bytes of data:Reply from 172.16.3.1: bytes=32 time=60ms TTL=241Reply from 172.16.3.1: bytes=32 time=60ms TTL=241Reply from 172.16.3.1: bytes=32 time=60ms TTL=241Reply from 172.16.3.1: bytes=32 time=60ms TTL=241Reply from 172.16.3.1: bytes=32 time=60ms TTL=241Ping statistics for 172.16.3.1:     Packets: Sent = 5, Received = 5, Lost = 0 (0% loss),Approximate round trip times in milli-seconds:     Minimum = 50ms, Maximum =  60ms, Average =  55ms
(3)本次实验的重点内容如下:

切换到R1特权模式下show ip route

R1#show ip routeCodes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default       U - per-user static routeGateway of last resort is not set     172.16.0.0/24 is subnetted, 2 subnetsC       172.16.2.0 is directly connected, Serial0/0C       172.16.1.0 is directly connected, Ethernet0/0

可以看出与R1直接相连的网络有两条:172.16.2.0和172.16.1.0

R1上分组转发到pc3上,需要自学习:算法如下:

启动rip算法

进入到全局配置模式下:

route  rip

路由配置模式下:

network 172.16.1.0 网络号

network 172.16.2.0

都是和R1直接相连的两个网络号

R1#configure terminalEnter configuration commands, one per line.  End with CNTL/Z.R1(config)#route ripR1(config-router)#network 172.16.1.0R1(config-router)#R1(config-router)#network 172.16.2.0R1(config-router)#exitR1(config)#exit


R2配置如下:

进入到全局配置模式下:

route  rip

路由配置模式下:

network 172.16.2.0 网络号

network 172.16.3.0

都是和R2直接相连的两个网络号


到次本次实验算是基本完成啦,

最后测试如下:

pc1到pc3

ping 172.16.3.2

C:>ping 172.16.3.2Pinging 172.16.3.2 with 32 bytes of data:Reply from 172.16.3.2: bytes=32 time=60ms TTL=241Reply from 172.16.3.2: bytes=32 time=60ms TTL=241Reply from 172.16.3.2: bytes=32 time=60ms TTL=241Reply from 172.16.3.2: bytes=32 time=60ms TTL=241Reply from 172.16.3.2: bytes=32 time=60ms TTL=241Ping statistics for 172.16.3.2:     Packets: Sent = 5, Received = 5, Lost = 0 (0% loss),Approximate round trip times in milli-seconds:     Minimum = 50ms, Maximum =  60ms, Average =  55msC:>

r1路由信息如下:

R1#show ip routeCodes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default       U - per-user static routeGateway of last resort is not set     172.16.0.0/24 is subnetted, 3 subnetsC       172.16.1.0 is directly connected, Serial0/0C       172.16.2.0 is directly connected, Ethernet0/0R       172.16.3.0 [120/1] via 172.16.3.1, 00:08:41, Serial0/0
pc3到pc1如下:

C:>ping 172.16.1.2Pinging 172.16.1.2 with 32 bytes of data:Request timed out.Request timed out.Request timed out.Request timed out.Request timed out.Ping statistics for 172.16.1.2:     Packets: Sent = 5, Received = 0, Lost = 5 (100% loss),Approximate round trip times in milli-seconds:     Minimum = 0ms, Maximum =  0ms, Average =  0ms

r2路由信息如下:

R2#show ip routeCodes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default       U - per-user static routeGateway of last resort is not set     172.16.0.0/24 is subnetted, 3 subnetsC       172.16.2.0 is directly connected, Serial0/0C       172.16.3.0 is directly connected, Ethernet0/0R       172.16.1.0 [120/1] via 172.16.2.1, 00:08:41, Serial0/0
         上面这行代码解释如下:1.0    这个为目的网络号  ,via经过2.0,通信时间,端口号。

至此测试完毕
