二、命令部署:
1、計算公式:
默認情況下K1和K3設為1,其他K值設為0,公式可以簡化為:(Bandwidth?+?Delay)?*?256

2、Metric增加1
R2(config)#router eigrp 90
R2(config-router)#offset-list 1 out 1 f0/0 經計算:Metric=158720
R1#show ip route eigrp
3.0.0.0/24 is subnetted, 1 subnets
D 3.3.3.0 [90/158720] via 12.1.1.2, 00:03:45, FastEthernet0/0

2、Metric增加1
R2(config)#router eigrp 90
R2(config-router)#offset-list 1 out 1 f0/0
三、驗證:
1、計算Metric並對比:
R1#show int f0/0
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec
R2#show int f1/0
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec
R3#show int lo1
MTU 1514 bytes, BW 8000000 Kbit, DLY 5000 usec
R1#show ip route eigrp
3.0.0.0/24 is subnetted, 1 subnets
D 3.3.3.0 [90/158720] via 12.1.1.2, 00:03:45, FastEthernet0/0
2、R2部署偏移列表,使3.3.3.3經過R2增加Metric 1
R1#show ip route eigrp
3.0.0.0/24 is subnetted, 1 subnets
D 3.3.3.0 [90/158721] via 12.1.1.2, 00:00:15, FastEthernet0/0
