二、配置Frame Relay

以Router2为例，其它两个路由器相似，\\\\后是人为添加的注释，在实际配置时不存在 Router>en \\\\进入特权配置模式

Router#conf t \\\\进入全局配置模式

Enter configuration commands, one per line. End with CNTL/Z. Router(config)#no ip domain-lookup \\\\取消名称解析 Router(config)#hostname Router2 \\\\配置路由器的名字 Router2(config)#int fa0/1 \\\\进入接口配置模式

Router2(config-if)#ip address 172.18.1.1 255.255.255.0 \\\\配置ip地址 Router2(config-if)#no shut \\\\激活端口

%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up

Router2(config-if)#int serial0/3/0

Router2(config-if)#encapsulation frame-relay \\\\对串口serial0/3/0进行frame-relay封装

Router2(config-if)#no shut

%LINK-5-CHANGED: Interface Serial0/3/0, changed state to up Router2(config-if)#

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/3/0, changed state to up Router2(config-if)#interface serial0/3/0.1 point-to-point \\\\进入串口的子接口配置模式

%LINK-5-CHANGED: Interface Serial0/3/0.1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/3/0.1, changed state to upRouter2

(config-subif)#ip address 192.168.1.1 255.255.255.0 \\\\为子接口配置IP地址 Router2(config-subif)#description Link Router1 DLCI 30 \\\\为子接口添加描述 Router2(config-subif)#frame-relay interface-dlci 40 \\\\配置DLCI Router2(config-subif)#interface serial0/3/0.2 point-to-point

%LINK-5-CHANGED: Interface Serial0/3/0.2, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/3/0.2, changed state to upRouter2

(config-subif)#ip address 192.168.3.1 255.255.255.0

Router2(config-subif)#description link to Router0 DLCI20 Router2(config-subif)#frame-relay interface-dlci 41 Router2(config-subif)#end

%SYS-5-CONFIG_I: Configured from console by console Router2#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router2(config)#router eigrp 100 \\\\在路由器上启用EIGRP路由协议 Router2(config-router)#network 172.18.0.0 \\\\通告与自己直接想连的网段 Router2(config-router)#network 192.168.3.0 Router2(config-router)#network 192.168.1.0
