首先告知：R1---R2;R2---R3;R4----R5:S1/0--S1/1都是这样的连中间的以太网用F0/0链接
R1----R2网段：12.1.1.0/24 R2-----R3:23.1.1.0/24
R1--R3----R4:134.1.1.0/24 R4---R5:45.1.1.0/24
需求：
1、R2的S1/0的带宽改为700K
2、R5为EIGRP STUB，只通告直连
3、R3启用loopback1:200.200.200.1/24,不通告进EIGRP去，但是要求全网都能访问这个环回
4、要确保R2的EIGRP在S1/0能使用至少70K的带宽，
5、R1和R2之间启用EIGRP的认证，PASSWORD自己设置
6、R4启用环回：loopback1---10,十个环回，172.16.1.0/24到10.0/24
7、R1、R2 R3 R5 只能收到R4的十个环回的一条汇总路由
8、修改R2的S1/1接口的hello--time 为20S
9、在R4做DHCP服务，要求R1和R3的F0/0地址要自动获取
10、要求从R2---TELNET--R5的5.5.5.5环回，登陆进去的时候却是登陆到了R4
11、要求从R2到R4形成非等价负载均衡
13、R1到R5五个路由器都启用环回Lo0，R1：Lo0:1.1.1.1/24 R2:Lo0:2.2.2.2/24以此类推。
12、全网EIGRP可达

这里就少做了一个非等价负载均衡，其他的都做完毕了！！
这个实验包含了：eigrp的非等价负载，邻居关系建立问题，认证、缺省路由配置，还有手工汇总等要点！同时也包含了DHCP和NAT的知识！
