基于labview的转速测量 LAB3EIGRP2实验
1>.配置基本eigrp。
2>.避免所有设备向不必要的接口发送EIGRP报文。
3>.要求总部收到的分部的路由条目尽可能少。
4>.要求实现分部访问internet服务器（80.80.80.80）,实现负载分担，internet路由器不得参加eigrp。
5>.R3和R4之间使用md5认证。
6>.配置R5为stub区域，且只能发送直连和汇总路由。
3 实验步骤和实验总结：0>.基础配置。

2>.避免所有设备向不必要的接口发送eigrp报文。
因为只有R5设置了loopback0口，所以只设置R5的loopback口为passive端口。
R5(config)#router eigrp 90
R5(config-router)#passive-interface loopback0
R5(config-router)#passive-interface loopback1
R5(config-router)#passive-interface loopback2
R5(config-router)#passive-interface loopback3

3>.要求总部收到的分部的路由条目尽可能少。
