帧中继拓扑连接：
router1的s0/0端口与FR的s0/0端口连接!
router2的s0/0端口与FR的s0/1端口连接!
router3的s0/0端口与FR的s0/2端口连接!
帧中继交换机的模拟配置：
- Router>enable
- Router# config term
- Router(config)# hostname FR
- FR(config)# frame-relay switching
- FR(config)# interface s0/0

- FR(config-if)# frame route 302 interface s0/2 203
- FR(config-if)# clock rate 64000
- FR(config-if)# no shutdown
- FR(config-if)# exit
验证：
这里Status为Inactive的原因是对端路由器还没有配置。
- FR#show fram route
- Input Intf Input Dlci Output Intf Output Dlci Status
- Serial0/0 102 Serial0/1 201 inactive
- Serial0/0 103 Serial0/2 301 inactive
- Serial0/1 201 Serial0/0 102 inactive
- Serial0/1 203 Serial0/2 302 inactive
- Serial0/2 301 Serial0/0 103 inactive
- Serial0/2 302 Serial0/1 203 inactive

- R3(config-if)# interface lo 3
- R3(config-if)# ip address 172.16.3.1 255.255.255.0
注意，在作DLCI 和IP 映射时，我们没有使用broadcast 参数!
验证：
- R1#show frame-relay map
- Serial0/0 (up): ip 192.168.1.2 dlci 102(0×66,0×1860), static,
- CISCO, status defined, active
- Serial0/0 (up): ip 192.168.1.3 dlci 103(0×67,0×1870), static,
- CISCO, status defined, active
- R1#ping 192.168.1.2
- Type escape sequence to abort.
- Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
- !!!!!
- Success rate is 100 percent (5/5), round-trip min/avg/max = 8/45/96 ms
- R1#ping 192.168.1.3
- Type escape sequence to abort.
- Sending 5, 100-byte ICMP Echos to 192.168.1.3, timeout is 2 seconds:
- !!!!!
- Success rate is 100 percent (5/5), round-trip min/avg/max = 16/51/100 ms
帧中继的路由器和交换机模拟配置的过程就是以上这些内容，命令比较多，应用起来复杂，所以读者需要认真和耐心了，关于EIGRP单播及带宽配置请阅读：
