1按拓扑配置IP地址
2启用EIGRP
R1(config)#router eigrp 1
R1(config-router)#no auto-summary
R1(config-router)#network 172.16.0.0
R1(config-router)#network 192.168.48.0
R1(config-router)#network 192.168.49.0
R1(config-router)#network 192.168.50.0
R1(config-router)#network 192.168.51.0
R1(config-router)#network 192.168.70.0
R2(config)#router eigrp 1
R2(config-router)#no auto-summary
R2(config-router)#network 172.16.0.0
3查看eigrp邻居
R1(config-router)#do show ip eig nei
