RIP计时器实验.docx

3.2RIP定时器情况?实验连接图提要描述RIP?定时器 更新定时器：30秒（用于设置定期路由更新的时间间隔） 无效定时器：180秒（路由器在认定一个路由成为无效路由之前所需要等待的时间） 保持定时器：180秒（用于设置路由信息被抑制的时间） 刷新定时器：240秒（用于设置某个路由成为无效路由并将它从路由表中删除的时间） 实验目标：通过实验调试RIP，观察定时器的情况，理解定时器的原理。基本配置R1的配置R2的配置! hostname R1 ! interface Loopback0 ?ip address 1.1.1.1 255.255.255.0 ! interface Serial1/1 ?no shut ?ip address 12.1.1.1 255.255.255.0 clock rate 64000 ! router rip ?network 0.0.0.0 !! hostname R2 ! interface Loopback0 ?ip address 2.2.2.2 255.255.255.0 ! interface Serial1/0 no shut ?ip address 12.1.1.2 255.255.255.0 ! interface Serial1/1 ?no shut ?ip address 23.1.1.2 255.255.255.0 ! router rip ?network 0.0.0.0 !R3的配置?! hostname R3 ! interface Loopback0 ?ip address 3.3.3.3 255.255.255.0 ! interface Serial1/0 ?no shut ?ip address 23.1.1.3 255.255.255.0 clock rate 64000 ! router rip network 0.0.0.0 !?↓调试配置及监测步骤↓查看各路由器路由表的情况： R1#show ip route ?????1.0.0.0/24 is subnetted, 1 subnets C???????1.1.1.0 is directly connected, Loopback0 R????2.0.0.0/8 [120/1] via 12.1.1.2,?00:00:00, Serial1/1 R????3.0.0.0/8 [120/2] via 12.1.1.2,?00:00:00, Serial1/1 R????23.0.0.0/8 [120/1] via 12.1.1.2,?00:00:00, Serial1/1 ?????12.0.0.0/24 is subnetted, 1 subnets C???????12.1.1.0 is directly connected, Serial1/1 R2#show ip route R????1.0.0.0/8 [120/1] via 12.1.1.1,?00:00:26, Serial1/0 ?????2.0.0.0/24 is subnetted, 1 subnets C???????2.2.2.0 is directly connected, Loopback0 R????3.0.0.0/8 [120/1] via 23.1.1.3,?00:00:10, Serial1/1 ?????23.0.0.0/24 is subnetted, 1 subnets C???????23.1.1.0 is directly connected, Serial1/1 ?????12.0.0.0/24 is subnetted, 1 subnets C???????12.1.1.0 is directly connected, Serial1/0 R3#show ip route R????1.0.0.0/8 [120/2] via 23.1.1.2,?00:00:20, Serial1/0 R????2.0.0.0/8 [120/1] via 23.1.1.2,?00:00:20, Serial1/0 ?????3.0.0.0/24 is subnetted, 1 subnets C???????3.3.3.0 is directly connected, Loopback0 ?????23.0.0.0/24 is subnetted, 1 subnets C???????23.1.1.0 is directly connected, Serial1/0 R????12.0.0.0/8 [120/1] via 23.1.1.2,?00:00:20,?S
