配置FR交换机：
[FR SWITCH]fr switching 开启FR SWITCH功能
[FR SWITCH]int s6/0
[FR SWITCH-Serial6/0]link-protocol fr ietf 接口封装FR
[FR SWITCH-Serial6/0]fr interface-type dce 设置接口模式DCE
[FR SWITCH-Serial6/0]fr dlci 20 为FR接口分配虚电路号
[FR SWITCH-fr-dlci-Serial6/0-20]quit
[FR SWITCH-Serial6/0]fr dlci 30
[FR SWITCH-fr-dlci-Serial6/0-30]quit
[FR SWITCH-Serial6/0]int s7/0
[FR SWITCH-Serial7/0]link-protocol fr ietf
[FR SWITCH-Serial7/0]fr interface-type dce
[FR SWITCH-Serial7/0]fr dlci 40
[FR SWITCH-fr-dlci-Serial7/0-40]quit
[FR SWITCH-Serial7/0]int s7/1

[FR SWITCH-Serial7/1]fr dlci 50
[FR SWITCH-fr-dlci-Serial7/1-50]quit
[FR SWITCH-Serial7/1]quit
[FR SWITCH]fr switch a-b interface s6/0 dlci 20 interface s7/0 dlci 40 配置DLCI路由
[FR SWITCH-fr-switching-a-b]quit
[FR SWITCH]fr switch a-c interface s6/0 dlci 30 interface s7/1 dlci 50
[FR SWITCH-fr-switching-a-c]quit
[FR SWITCH]disp fr switch-table all
Total PVC switch records:2
PVC-Name Status Interface(Dlci) <-----> Interface(Dlci)
a-b Active Serial6/0(20) Serial7/0(40)
a-c Active Serial6/0(30) Serial7/1(50)
此时的FR switch已经配置成功，都为active状态。
此时RTA,RTB,RTC间可以互访：

在每个路由器上配置loop接口来验证连通性：
[RTA]int loop0
[RTA-LoopBack0]ip add 20.0.0.1 32
[RTA]rip 1
[RTA-rip-1]ver 2
[RTA-rip-1]undo su
[RTA-rip-1]undo summary
[RTA-rip-1]network 10.1.1.0
[RTA-rip-1]network 20.0.0.0
[RTB]int loop0
[RTB-LoopBack0]ip add 30.0.0.1 32
[RTB-LoopBack0]quit
[RTB]rip 1
[RTB-rip-1]ver 2
[RTB-rip-1]undo summary
[RTB-rip-1]network 10.1.1.0
[RTB-rip-1]network 30.0.0.0
[RTB-rip-1]quit
[RTC]int loop0
[RTC-LoopBack0]ip add 40.0.0.1 32
[RTC-LoopBack0]quit
[RTC]rip 1
[RTC-rip-1]ver 2
[RTC-rip-1]undo summary
[RTC-rip-1]network 10.1.1.0
[RTC-rip-1]network 40.0.0.0
[RTC-rip-1]quit
此时却无法学习到路由信息，因为FR不支持RIP更新广播发送，默认为P2P模式：
[RTA]disp ip routing-table
Routing Tables: Public
Destinations : 7 Routes : 7
Destination/Mask Proto Pre Cost NextHop Interface
10.1.1.0/24 Direct 0 0 10.1.1.1 S1/0
10.1.1.1/32 Direct 0 0 127.0.0.1 InLoop0
10.1.1.2/32 Direct 0 0 10.1.1.2 S1/0
10.1.1.3/32 Direct 0 0 10.1.1.3 S1/0
20.0.0.1/32 Direct 0 0 127.0.0.1 InLoop0
127.0.0.0/8 Direct 0 0 127.0.0.1 InLoop0
127.0.0.1/32 Direct 0 0 127.0.0.1 InLoop0
要成功学习到路由信息必须配置RIP的邻居信息perr地址，使其通过单播发送更新：
[RTA]rip 1
[RTA-rip-1]peer 10.1.1.2
[RTA-rip-1]peer 10.1.1.3
[RTB]rip 1
[RTB-rip-1]peer 10.1.1.1
[RTB-rip-1]peer 10.1.1.3
[RTC]rip 1
[RTC-rip-1]peer 10.1.1.1
[RTC-rip-1]peer 10.1.1.2
此时路由表上已有所有RIP的路由信息：
[RTA]disp ip routing-table
Routing Tables: Public
Destinations : 9 Routes : 9
Destination/Mask Proto Pre Cost NextHop Interface
10.1.1.0/24 Direct 0 0 10.1.1.1 S0/0
10.1.1.1/32 Direct 0 0 127.0.0.1 InLoop0
10.1.1.2/32 Direct 0 0 10.1.1.2 S0/0
10.1.1.3/32 Direct 0 0 10.1.1.3 S0/0
20.0.0.1/32 Direct 0 0 127.0.0.1 InLoop0
30.0.0.1/32 RIP 100 1 10.1.1.2 S0/0
40.0.0.1/32 RIP 100 1 10.1.1.3 S0/0
127.0.0.0/8 Direct 0 0 127.0.0.1 InLoop0
127.0.0.1/32 Direct 0 0 127.0.0.1 InLoop0
