帧中继全网拓扑试验配置
公司总部和分支机构的通信除了用DDN之外，另外还可以采用帧中继。路由器A是总公司，B和C是分支机构，利用帧中继通信的具体配置可以如下：
试验环境：
首先要清楚全网示意图：
A：连接帧中继的端口：202.110.100.1 255.255.255.0
局域网端口192.168.10.1 255.255.255.0
B：连接帧中继的端口：202.110.100.2 255.255.255.0
局域网端口192.168.10.2 255.255.255.0
C：连接帧中继的端口：202.110.100.3 255.255.255.0
局域网端口192.168.10.3 255.255.255.0
通过对帧中继的配置，实现不同网段间的通信，那么试验就成功了。
在 A 上做：
router>en
Router#config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#host A
A(config)#int e0
A(config-if)#ip addr 192.168.10.1 255.255.255.0
A(config-if)#no shut
%LINK-3-UPDOWN: Interface Ethernet0, changed state to up

B(config-if)#exit
B(config)#router eigrp 100
B(config-router)#net 192.168.20.0
B(config-router)#net 202.110.100.0
B(config-router)#exit
B(config)#^Z
%SYS-5-CONFIG_I: Configured from console by console
在 C 上做：
Router>
Router>en
Router#config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#host C
C(config)#int e0
C(config-if)#ip addr 192.168.30.1 255.255.255.0
C(config-if)#no shut
%LINK-3-UPDOWN: Interface Ethernet0, changed state to up
C(config-if)#int s0
C(config-if)#ip addr 202.110.100.3 255.255.255.0
C(config-if)#encap frame-relay
C(config-if)#frame-relay int
C(config-if)#frame-relay interface-dlci 301
C(config-if)#frame-relay interface-dlci 302
C(config-if)#bandwidth 64
C(config-if)#no shut
%LINK-3-UPDOWN: Interface Serial0, changed state to up
C(config-if)#exit
C(config)#router eigrp 100
C(config-router)#net 202.110.100.0
C(config-router)#net 192.168.30.0
C(config-router)#exit
C(config)#exit
