12-高級路由:EIGRP 非等價負載均衡
Note:
做EIGRP非等價負載均衡需要關閉思科自帶的CDP協議。
二、命令部署:
1、查看R1 EIGRP拓撲中所有路由條目
R1#show ip eigrp topology all-links 可以看大次優路徑路由條目
2、調整R2 f0/0延遲,使其延遲變小:
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調V值, 次優路徑FD < 使得最優路徑FD×V值
R1(config)#router eigrp 90
R1(config-router)#variance 15
三、驗證:
1、基本部署完成後,R1路由表中關於3.3.3.3只有1條路徑:
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、調整R2 f0/0延遲,使其延遲變小:使得AD < FD
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、驗證R1的3.3.3.3有2條路徑
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、抓包驗證是否是按1:15包發送的
