实验一、配置Eigrp 验证，汇总

  环境：三台路由器串口相连，其它接口配置如图

  要求：1.配置EIGRP关闭自动路由汇总

2.在R1的三个LOOP口进行EIGRP手工路由汇总

3.R2、R3配置EIGRP接口密文验证

4.验证并测试结果

 

 

 

 

步骤一： 配置三个路由器接口使其连通。

 

R1的配置

R1(config)# interface Loopback0

R1(config-if)# ip address 30.1.1.1 255.255.255.0

R1(config)# interface Loopback1

R1(config-if)# ip address 30.1.2.1 255.255.255.0

R1(config)# interface Loopback2

R1(config-if)# ip address 30.1.3.1 255.255.255.0

R1(config)# interface s0

R1(config-if)# ip address 10.1.1.2 255.255.255.0

R1(config-if)#no shutdown

 

R2的配置

R2(config)# interface s0

R2(config-if)# ip address 10.1.1.1 255.255.255.0

R2(config-if)#clockrate 64000

R2(config-if)#no shutdown

 

R2(config)# interface s1

R2(config-if)# ip address 20.1.1.1 255.255.255.0

R12(config-if)#no shutdown

 

R3的配置

R3(config)# interface Loopback0

R3(config-if)# ip address 40.1.1.1 255.255.255.0

R3(config)# interface s1

R3(config-if)# ip address 20.1.1.2 255.255.255.0

R3(config-if)#clockrate 64000

R3(config-if)#no shutdown

 

步骤二： 配置Eigrp

 

R1的配置

R1(config)# router eigrp 100  à启用eigrp，自治号为100，三台路由器保持一致

R1(config-router)# network 10.1.1.0 0.0.0.255  à使相关接口参与eigrp

R1(config-router)# network 30.1.1.0 0.0.0.255

R1(config-router)# network 30.1.2.0 0.0.0.255

R1(config-router)# network 30.1.3.0 0.0.0.255

R1(config-router)# no auto-summary       à关闭自动汇总

 

R2的配置

R2(config)# router eigrp 100 

R2(config-router)# network 10.1.1.0 0.0.0.255

R2(config-router)# network 20.1.1.0 0.0.0.255

R2(config-router)# no auto-summary

 

R3的配置

R3(config)# router eigrp 100

R3(config-router)# network 20.1.1.0 0.0.0.255

R3(config-router)# network 40.1.1.0 0.0.0.255

R3(config-router)# no auto-summary

 

 

步骤三：配置EIGRP手工路由汇总

 

R1的配置

R1(config)# interface s0

R1(config-if)# ip summary-address eigrp 100 30.1.0.0 255.255.252.0 à手工汇总路由

 

 

步骤四：在r2和r3上配置EIGRP 验证

 

R2的配置

R2(config)# key chain cisco  à定义chain名称

R2(config-keychain)# key 1  àkey值编号，须一致

R2(config-keychain-key)# key-string aaa  à定义密钥，须一致

R2(config)# interface s1

R2(config-if)# ip authentication mode eigrp 100 md5  à启用eigrp验证模式md5

R2(config-if)# ip authentication key-chain eigrp 100 cisco  à将chain应用到验证

 

R3的配置

R3(config)# key chain cisco

R3(config-keychain)# key 1

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

R3(config)# interface s1

R3(config-if)# ip authentication mode eigrp 100 md5

R3(config-if)# ip authentication key-chain eigrp 100 cisco
