CCNP之BSCI实验3 理解EIGRP的拓扑表，后继，FD,AD

CCNP之BSCI实验3 理解EIGRP的拓扑表，后继，FD,AD
实验目的：
1.理解EIGRP的拓扑表
2.理解后继，可行后继，可行距离FD及通告距离AD
3.使用DEBUG命令来查看拓扑改变
实验拓扑：如图

实验步骤：
1.按照图给每个路由器配置相应环回口及IP地址
2.配置串行链路的接口，配置时钟频率和带宽
3.配置EIGRP
4.使用DEBUG ip eigrp 1 查看在邻接建立后EIGRP安装路由的过程
5.查看EIGRP的邻居关系
6。注意观察拓扑表，及AD和FD
注：带宽值指到达目标网络带宽的最低值
延迟指延迟之和
MTU指到达目标网络带宽的最小值
条数公表示目标网络可达，并为参与度量运算
