实验拓扑图如上:
本文属于个人学习笔记整理,
帧中继OSPF点到多点模式(广播):
配置步骤:1、配置FR,强制支持广播;2、配置OSPF;3、修改模式为点到多点;
实验目的:达到全网互通!

=================================================================
首先帧中继FR配置:
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hos HR
HR(config)#frame-relay switching 开启帧中继
HR(config)#int s0/0
HR(config-if)#encapsulation frame-relay
HR(config-if)#frame-relay intf-type dce 帧中继接口都配置为DCE
HR(config-if)#clock rate 64000 DCE别忘记设置时钟频率
HR(config-if)#frame-relay route 103 int s0/1 301
HR(config-if)#frame-relay route 104 int s0/2 401
HR(config-if)#no shu
HR(config-if)#exit
HR(config)#int s0/1
HR(config-if)#encapsulation frame-relay
HR(config-if)#frame-relay intf-type
HR(config-if)#frame-relay intf-type dce
HR(config-if)#clock rate 64000
HR(config-if)#frame-relay route 301 int s0/0 103
HR(config-if)#no shu
HR(config-if)#exit
HR(config)#int s0/2
HR(config-if)#encapsulation frame-relay
HR(config-if)#frame-relay intf-type dce

HR(config-if)#frame-relay route 401 int s0/0 104
HR(config-if)#no shu
HR(config-if)#exit
