一、实验拓扑: Note: 做EIGRP非等价负载均衡需要关闭思科自带的CDP协议。 二、命令部署: 1、查看R1 EIGRP拓扑中所有路由条目 R1#show ip eigrp topology all-links 可以看大次优路径路由条目

2、调整R2 f0/0延迟,使其延迟变小: R2#show int f0/0 MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec

R2(config)#int f0/0 R2(config-if)#delay 9

3、R1调V值, 次优路径FD < 使得最优路径FD×V值 R1(config)#router eigrp 90 R1(config-router)#variance 15

三、验证: 1、基本部署完成后,R1路由表中关于3.3.3.3只有1条路径: ①R1#show ip route 3.0.0.0/24 is subnetted, 1 subnets D 3.3.3.0 [90/156160] via 13.1.1.3, 00:00:11, FastEthernet0/0

②R1#show ip eigrp topology all-links P 3.3.3.0/24, 1 successors, FD is 156160, serno 8 via 13.1.1.3 (156160/128256), FastEthernet0/0 via 12.1.1.2 (2300416/156160), Serial3/0 2、调整R2 f0/0延迟,使其延迟变小:使得AD < FD R1#show ip eigrp topology all-links P 3.3.3.0/24, 1 successors, FD is 156160, serno 8 via 13.1.1.3 (156160/128256), FastEthernet0/0 via 12.1.1.2 (2298112/153856), Serial3/0

3、验证R1的3.3.3.3有2条路径 R1#show ip route 3.0.0.0/24 is subnetted, 1 subnets D 3.3.3.0 [90/156160] via 13.1.1.3, 00:00:05, FastEthernet0/0 [90/2300160] via 12.1.1.2, 00:00:05, Serial3/0

4、抓包验证是否是按1:15包发送的
