详解BSCI实验一、配置EIGRP 验证,汇总

简介:
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  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
