RIPv2的认证和触发更新

RIPv2的认证和触发更新

1、  实验目的:

通过本次的使用,我们可以掌握如下技能

1)        RIPv2明文认证的配置和匹配原则。

2)        RIPv2 MD5认证的配置和匹配原则。

3)        RIPv2的触发更新。

2、  实验拓扑图:

3、  实验步骤:

1)根据网络拓扑图说明,配置各个接口的地址。

R!(config)#hostname R1

R1(config)#interface loopback 0

R1(config-if)#ip ad

R1(config-if)#ip address 1.1.1.1 255.255.255.0

2)启用RIPV2

R1(config)#router rip

R1(config-router)#ver

R1(config-router)#version 2

R1(config-router)#network 1.0.0.0

R1(config-router)#network 192.1681.0

R1(config-router)#

注:启用RIPv2,并将去网络发布出去

R2(config)#router rip

R2(config-router)#ver

R2(config-router)#version 2

R2(config-router)#no au

R2(config-router)#no auto-summary

R2(config-router)#net

R2(config-router)#network 192.168.1.0

R2(config-router)#network 192.168.2.0

R2(config-router)#

 

 

R3(config)#router rip

R3(config-router)#ve

R3(config-router)#version 2

R3(config-router)#net

R3(config-router)#network 192.168.2.0

R3(config-router)#network 192.168.3.0

R3(config-router)#

 

 

R4(config)#router rip

R4(config-router)#ve

R4(config-router)#version 2

R4(config-router)#no au

R4(config-router)#no auto-summary

R4(config-router)#network 192.168.3.0

3)配置RIPv2的认证

R1(config)#key chain xia

R1(config-keychain)#key 1

R1(config-keychain-key)#key-string xiajiang

R1(config-keychain-key)#exit

R1(config)#interface serial 0/0

R1(config-if)#ip rip authentication ke

R1(config-if)#ip rip authentication key-chain xia

R1(config-if)#ip rip triggered

R1(config-if)#

注:启用RIPv2的认证

 

 

R2(config)#key chain xia

R2(config-keychain)#key 1

R2(config-keychain-key)#ke

R2(config-keychain-key)#key-string xiajiang

R2(config-keychain-key)#end

R2(config)#interface s0/0

R2(config-if)#ip r

R2(config-if)#ip ri

R2(config-if)#ip rip tri

R2(config-if)#ip rip triggered

R2(config-if)#ip rip authentication key-chain xia

R2(config-if)#exit

R2(config)#interface serial 0/1

R2(config-if)#ip rip authentication key-chain xia

R2(config-if)#ip rip triggered

R2(config-if)#

 

 

R3(config)#key chain xia

R3(config-keychain)#key 1

R3(config-keychain-key)#key-string xiajiang

R3(config-keychain-key)#exit

R3(config-keychain)#exit

R3(config)#interface serial 0/1

R3(config-if)#ip rip authentication key-chain xia

R3(config-if)#ip rip triggered

R3(config-if)#exit

R3(config)#interface serial 0/2

R3(config-if)#ip rip authentication key-chain xia

R3(config-if)#ip rip triggered

R3(config-if)#

 

 

R4(config)#key chain xia

R4(config-keychain)#key 1

R4(config)#interface serial 0/2

R4(config-if)#ip rip authentication key-chain xia

R4(config-if)#ip rip triggered

R4(config-if)#

4)测试配置情况

R1#show ip pro

R1#show ip protocols

Routing Protocol is "rip"

  Sending updates every 30 seconds, next due in 1 seconds

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

  Outgoing update filter list for all interfaces is not set

  Incoming update filter list for all interfaces is not set

  Redistributing: rip

  Default version control: send version 2, receive version 2

    Interface             Send  Recv  Triggered RIP  Key-chain

    Serial0/0             2     2          Yes       xia            

    Loopback0             2     2                                   

  Automatic network summarization is in effect

  Maximum path: 4

  Routing for Networks:

    1.0.0.0

    192.168.1.0

  Routing Information Sources:

    Gateway         Distance      Last Update

    192.168.1.2          120      00:00:19

  Distance: (default is 120)

R1#

注:由上面的Serial0/0             2     2          Yes       xia表明已经在上Serial0/0启用了触发更新

 

 

R2#show ip rip dat

R2#show ip rip database

1.0.0.0/8    auto-summary

1.0.0.0/8

    [1] via 192.168.1.1, 00:02:48 (permanent), Serial0/0

   * Triggered Routes:

     - [1] via 192.168.1.1, Serial0/0

192.168.1.0/24    auto-summary

192.168.1.0/24    directly connected, Serial0/0

192.168.2.0/24    auto-summary

192.168.2.0/24    directly connected, Serial0/1

192.168.3.0/24    auto-summary

192.168.3.0/24

    [1] via 192.168.2.2, 00:01:13 (permanent), Serial0/1

   * Triggered Routes:

     - [1] via 192.168.2.2, Serial0/1

R2#

注:从路由器R2rip数据值可以进一步的看出,在Serial0/0Serial0/1启用了触发更新。

 

如果想启用MD5认证,只要在接口下声明模式为MD5即可,具体配置命令如下:

R1(config-keychain)#key 1

R1(config-keychain-key)#key-string xiajiang

R1(config)#interface serial 0/0

R1(config-if)#ip rip authentication mode md5

R1(config-if)#ip rip authentication key-chain xia

R1(config-if)#ip rip triggered

R1(config-if)#

具体怎样去配置MD5认证,这里就不在多说了。OK,到此实验结束!!!!!!!!
