3.7        实验5:配置帧中继流量×××及OSPF的配置

3.7.1         实验内容

 
l        此次实验的拓扑是一个全网状的帧中继网络
l        在网络中配置OSPF路由协议
l        布署帧中继流量×××
u       在R5路由器是配置流量×××,本地端口速率为1.544Mbit/s
u       R5R3PVCCIR32kbit/s
u       R3本地端口速率为64kbit/s,对此PVC进行流量×××

3.7.2         实验拓扑

安照图3-8这个拓扑图进行实验

3.7.3         所需设备

l        4台路由器,一台配置为帧中继交换机
l        3条背对背线缆
l        PC一台

3.7.4         实验步骤

1步 安照帧中继的配置步骤R5帧中继封装
2步 配置地址静态映射
3步 配置路由协议
4步 启动FRTS
5步 为每条PVC配置一个映射类
6步 在子接口上应用帧中继映射类
在本实验中只在R5R3PVC上做流量×××。
