实验 21:配置EIGRP等价和不等价load-balancing
实验目标:
    1.学会配置EIGRP不等价loadbalancing
实验步骤:
    1.查看并修改serial接口参考带宽,并修改为1544K.
    2.查看R1、R2之间的等价load-balancing.
    3.在R2、R3上配置不等价load-balancing.
1.查看并修改serial接口参考带宽,并修改为1544K.
查看R2 serial接口带宽为128Kbit.
R2(config)#do show inter s0/3/0
Serial0/3/0 is up, line protocol is up (connected)
  Hardware is HD64570
  Internet address is 192.168.230.1/24
  MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec,
R2(config)#inter s0/3/0
R2(config-if)#bandwidth 1544
R3(config)#inter s0/3/0
R3(config-if)#bandwidth 1544
2.查看R1、R2之间的等价load-balancing.
R2(config)#do show ip eigrp topology
IP-EIGRP Topology Table for AS 100/ID(192.168.2.1)
P 172.16.0.0/22, 2 successors, FD is 156160
         via 192.168.12.1 (156160/128256), FastEthernet0/0
         via 192.168.120.1 (156160/128256), FastEthernet0/1
3.在R2、R3上配置不等价load-balancing.
应该用两条线的Metric值的比例来算不等价load-balancing的比例，
然后取刚好大于或者等于算出来的值的整数。
R2(config)#do show ip eigrp topology
IP-EIGRP Topology Table for AS 100/ID(192.168.2.1)
P 192.168.3.0/24, 1 successors, FD is 156160
         via 192.168.23.2 (156160/128256), FastEthernet1/0
         via 192.168.230.2 (2297856/128256), Serial0/3/0
配置R2去R3的不等价load-balancing
R2(config)#router ei 100
R2(config-router)#variance 15
一般也配置R3回来的不等价load-balancing
R3(config)#router ei 100
R3(config-router)#variance 15
