RIPv2基本配置

1.實驗目的

通過實驗掌握:

(1)在路由器上啟動RIPv2路由進程

(2)啟用參與路由協議的接口,並且通告網絡

(3)auto-summary的開啟和關閉

(4)查看和調試RIPv2路由協議相關信息

2.拓撲結構

R0:

R0(config)#int lo0

R0(config-if)#ip add 1.1.1.1 255.255.255.0

R0(config-if)#no sh

R0(config-if)#int s0/0

R0(config-if)#ip add 12.1.1.1 255.255.255.0

R0(config-if)#clo r 64000

R0(config-if)#no sh

R0(config-if)#exit

R0(config)#router rip

R0(config-router)#v 2

R0(config-router)#network 1.0.0.0

R0(config-router)#network 12.0.0.0

R0(config-router)#no auto-summary    //關閉自動匯總

R1:

R1(config)#int lo0

R1(config-if)#ip add 2.2.2.2 255.255.255.0

R1(config-if)#no sh

R1(config-if)#int s0/1

R1(config-if)#ip add 12.1.1.2 255.255.255.0

R1(config-if)#no sh

R1(config-if)#int s0/0

R1(config-if)#ip add 13.1.1.1 255.255.255.0

R1(config-if)#clo r 64000

R1(config-if)#no sh

R1(config-if)#exit

R1(config)#router rip

R1(config-router)#v 2

R1(config-router)#no auto-summary

R1(config-router)#network 12.0.0.0

R1(config-router)#network 13.0.0.0

R1(config-router)#network 2.0.0.0

R2:

R2(config)#int lo0

R2(config-if)#ip add 3.3.3.3 255.255.255.0

R2(config-if)#no sh

R2(config-if)#int s0/1

R2(config-if)#ip add 13.1.1.2 255.255.255.0

R2(config-if)#no sh

R2(config-if)#exit

R2(config)#router rip

R2(config-router)#v 2

R2(config-router)#no auto-summary

R2(config-router)#network 13.0.0.0

R2(config-router)#network 3.0.0.0

4.實驗調試

(1) show ip route

R0#sh ip ro

Codes: C – connected, S – static, R – RIP, M – mobile, B – BGP

       D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area

       N1 – OSPF NSSA external type 1, N2 – OSPF NSSA external type 2

       E1 – OSPF external type 1, E2 – OSPF external type 2

       i – IS-IS, su – IS-IS summary, L1 – IS-IS level-1, L2 – IS-IS level-2

       ia – IS-IS inter area, * – candidate default, U – per-user static route

       o – ODR, P – periodic downloaded static route

Gateway of last resort is not set

     1.0.0.0/24 is subnetted, 1 subnets

C       1.1.1.0 is directly connected, Loopback0

     2.0.0.0/24 is subnetted, 1 subnets

R       2.2.2.0 [120/1] via 12.1.1.2, 00:00:09, Serial0/0

     3.0.0.0/24 is subnetted, 1 subnets

R       3.3.3.0 [120/2] via 12.1.1.2, 00:00:09, Serial0/0

     12.0.0.0/24 is subnetted, 1 subnets

C       12.1.1.0 is directly connected, Serial0/0

     13.0.0.0/24 is subnetted, 1 subnets

R       13.1.1.0 [120/1] via 12.1.1.2, 00:00:09, Serial0/0

(2)show ip protocols

R0#sh ip pro

Routing Protocol is "rip"

 Outgoing update filter list for all interfaces is not set

 Incoming update filter list for all interfaces is not set

 Sending updates every 30 seconds, next due in 11 seconds

 Invalid after 180 seconds, hold down 180, flushed after 240

 Redistributing: rip

 Default version control: send version 2, receive version 2

    Interface            Send Recv Triggered RIP Key-chain

    Serial0/0             2     2                                   

    Loopback0             2     2                           

 Automatic network summarization is not in effect

 Maximum path: 4

 Routing for Networks:

    1.0.0.0

    12.0.0.0

 Routing Information Sources:

    Gateway         Distance      Last Update

    12.1.1.2             120      00:00:21

 Distance: (default is 120)

// RIPv2默認情況下只接收和發送版本2的路由更新

注意: 

可以通過命令「ip rip send version」和「ip rip receive version」來控制在路由器接口上接收和發送的版本。

例如在s0/0接口上接收版本1和2的路由更新,但是只發送版本2的路由更新,配置如下:

R0(config-if)#ip rip send version 2

R0(config-if)#ip rip receive version 1 2

接口特性是優於進程特性的,雖然在RIP進程中配置了「version 2」 , 但是如果在接口上配置了「ip rip receive version 1 2」 ,則該接口可以接收版本1和 2的路由更新。
