CCIE EIGRP综合实验

最近看一个老师讲EIGRP，留了一个综合实验，感觉很有意思，给大家分享一下：

实验需求：
1：R1,2,3,5运行EIGRP100，且关闭自动汇总；
2：指定route-id为环回口；
3：R1不能从环回口接收和发送任何EIGRP信息；
4：运行EIGRP100的路由器，HOP count超过10，路由信息将无效；
5：R1，2，3hello时间10S。Dead时间30S；
6：帧中继网络中使用认证，key-chain=killccie  key=10  password=killccie10；
7：当R2,3的以太网断掉，保证R2,3的环回口可以通信；
8：R1环回口down，发出query包，2分钟得不到回应就重置邻居关系；
9：R5，6串行链路封装PPP，CHAP认证，单播建立EIGRP 200邻居；
10：EIGRP关闭自动汇总，不可以出现32位路由；
11：R5在EIGRP200中只用bandwidth决定metric；
12：R6,5之间带宽修改为700K，EIGRP使用70K的带宽；
13：R5做EIGRP双向重分布；
14：R1的loopback14修改delay为100，要求R2,3看到一条汇总路由，验证metric为最小的 那个；
15：在R6环回口创建多地址，并通告进RIPV2；
16：在R5上看到DX的R6路由，R2,3只能看到D的路由；
17：R3启用环回口不通告进EIGRP100中，但要求全网能够访问，要求使用ip default-network；
18：在R6上，只允许R1的loopback100能telnetR6的6.6.6.6；
19：配置R6不接收任何EIGRP200的QUERY；
20：R6可以给EIGRP200的邻居发送直连，汇总，重分布的信息。

总结一下，个人感觉该实验没什么特别难点，有几个重点还是需要注意一下的：
1：telnet源接口，这个用的应该会很多；
2：EIGRP中route-id的作用。
个人感觉这个主要是用来重分布之后做标记，可以防止环路。有待考究，呵呵。
