复习之帧中继交换网络实例一

配置帧中继时,请使用以下的几个步骤:
帧中继交换机:
1.启用frame-relay switching
2.接口没有IP,启用encapsulation frame-relay
3.配置intf-type DCE接口配置为DCE>>需要配置时钟
4.配置lmi-type信令.(默认为cisco.可选的有ansi,q933a)
5.使用frame-relay route做接口路由
frame-relay route 101 (本接口的DLCI值) interface s2/1 202(对方接口s2/1的DLCI)

帧中继交换机间路由的是DLCI值,并不关心IP地址.
帧中继客户端:
1.启用encapsulation frame-relay,设置IP
2.配置lmi-type信令.(默认为cisco.可选的有ansi,q933a,需要跟帧中继交换端一样)
3.配置frame-relay map
fram-relay map ip   10.0.0.1(对方IP) 104 (本地DLCI值)

以下为配置内容:(只记录了关键的部分)
