文档介绍：使用帧中继交换机
实验拓扑

192- 168* 1- 2 192- 168- 1-3
R3(config-if)#do ping
R1(co nfig-if)#
配置示例
, timeout is 2 seconds: !!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/47/88 ms R3(config-if)#
全网互通
R3(config-if)#do show fram ma
Serial1/0 (up): ip dlci 301(0x12D,0x48D0), static,
CISCO, status defined, active
Serial1/0 (up): ip dlci 302(0x12E,0x48E0), static,
CISCO, status defined, active
R3(config-if)# 使用的是静态映射
使用路由器模拟帧中继交换机
实验拓扑
R2
R1(config-if)# frame-relay intf-type dce // 帧中继交换机作为 DCE端
配置示例
1. R1模拟帧中继交换机配置脚本
配置如下
R1>e n
R1#conft
R1(config)# frame-relay switching //把路由器设置为帧中继交换机
R1(co nfig)#i nt s 1/0
R1(config-if)#no sh
R1(c on fig-if)# no ip add
R1(c on fig-if)#e ncapsulati on frame-relay
R1(config-if)#clock rate 64000
R1(config-if)# frame-relay lmi-type ansi // 设置帧中继协议为 ansi
R1(config-if)#serial restart-delay 0
// 设置帧中继内部交换
R1(config-if)# frame-relay route 203 interface s 1/1 302
R1(config-if)#frame-relay route 204 interface s 1/2 402
R1(config-if)#int s 1/1
R1(config-if)#no sh
R1(config-if)#no ip add
R1(config-if)#encapsulation frame-relay
R1(config-if)#frame-relay lmi-type ansi
R1(config-if)#frame-relay intf-type dce
R1(config-if)#serial restart-delay 0
R1(config-if)#frame-relay route 302 interface serial 1/0 203
R1(config-if)#frame-relay route 304 interface s 1/2 403
R1(config-if)#int s 1/2
R1(config-if)#no sh
R1(config-if)#no ip add
R1(config-if)#encapsulation frame-relay
R1(config-if)#serial restart-delay 0
R1(config-if)#clock rate 64000
R1(config-if)#frame-relay lmi-type ansi
R1(config-if)#frame-relay intf-type dce
R1(config-if)#frame-relay route 402 int s 1/0 204
R1(config-if)#fra route 403 int s 1/1 304
2. 其他路由器配置脚本
R2
R2>en
R2#conf t
R2(config)#int s 1/0
R2(config-if)#no sh
R2(config-if)#ip add
R2(config-if)#encapsulation frame-relay
R2(config-if)#serial restart-delay 0
