二:配置过程
1:修改R1,R2,R3之间的链路带宽为64Kbps
R1(config)#int s2/1
R1(config-if)#bandwidth 64
R1(config-if)#int f0/0
R1(config-if)#bandwidth 64
R2(config)#int s2/1
R2(config-if)#bandwidth 64
R2(config-if)#int s2/2
R2(config-if)#bandwidth 64
R3(config)#int s2/1
R3(config-if)#bandwidth 64
R3(config-if)#int f0/0
R3(config-if)#bandwidth 64
2:配置EIGRP
R1(config)#router eigrp 100
R1(config-router)#no au
R1(config-router)#net 10.0.0.0

R1(config-router)#net 1.1.1.1
R2(config)#router eigrp 100
R2(config-router)#no au
R2(config-router)#net 10.0.0.0
R2(config-router)#net 2.2.2.2
R2(config-router)#net 23.0.0.0
R2(config-router)#net 192.168.0.0
R3(config)#router eigrp 100
R3(config-router)#no au
R3(config-router)#net 10.0.0.0
R3(config-router)#net 3.3.3.3
R3(config-router)#net 172.16.0.0
R3(config-router)#net 23.0.0.0
