4.8 Frame-Relay&RIPv2
实验目的:
1、掌握帧中继上部署RIPv2。
2、通过部署RIPv2实现不同分支之间的通信。
实验拓扑:
实验步骤:
1、依据图中拓扑,通过路由器模拟帧中继交换机,配置如下:
①开启帧中继交换功能
FW-SW(config)#frame-relay switching
②接口开启帧中继封装,并定义为DCE接口
FW-SW(config)#int s0/0
FW-SW(config-if)#no shutdown
FW-SW(config-if)#encapsulation frame-relay
FW-SW(config-if)#frame-relay intf-type dce
FW-SW(config-if)#exit
FW-SW(config)#int s0/1
FW-SW(config-if)#no shutdown
FW-SW(config-if)#encapsulation frame-relay
FW-SW(config-if)#frame-relay intf-type dce
FW-SW(config-if)#exit
FW-SW(config)#int s0/2
FW-SW(config-if)#no shutdown
FW-SW(config-if)#encapsulation frame-relay
FW-SW(config-if)#frame-relay intf-type dce
FW-SW(config-if)#exit
③编写帧中继转发条目
FW-SW(config)#int s0/0
FW-SW(config-if)#frame-relay route 102 interface s0/1 201
FW-SW(config-if)#frame-relay route 103 interface s0/0 301
FW-SW(config-if)#exit
FW-SW(config)#int s0/1
FW-SW(config-if)#frame-relay route 201 interface s0/0 102
FW-SW(config-if)#exit
FW-SW(config)#int s0/2
FW-SW(config-if)#frame-relay route 301 interface s0/0 103
FW-SW(config-if)#exit
2、通过部署帧中继技术,使得各个站点直连连通,其中R1为中心点,R2和R3为分支点,配置如下:
R1上
R1(config)#int s0/0
R1(config-if)#no shutdown
R1(config-if)#encapsulation frame-relay
R1(config-if)#no frame-relay inverse-arp
R1(config-if)#frame-relay map ip 192.168.1.2 102 broadcast
R1(config-if)#frame-relay map ip 192.168.1.3 103 broadcast
R1(config-if)#exit
R2上
R2(config)#int s0/0
R2(config-if)#no shutdown
R2(config-if)#encapsulation frame-relay
R2(config-if)#no frame-relay inverse-arp
R2(config-if)#frame-relay map ip 192.168.1.1 201 broadcast
R2(config-if)#frame-relay map ip 192.168.1.3 201 broadcast
R2(config-if)#exit
R3上
R3(config)#int s0/0
R3(config-if)#no shutdown
R3(config-if)#encapsulation frame-relay
R3(config-if)#no frame-relay inverse-arp
R3(config-if)#frame-relay map ip 192.168.1.1 301 broadcast
R3(config-if)#frame-relay map ip 192.168.1.2 301 broadcast
R3(config-if)#exit
测试直连连通性,如下:
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 = 36/42/60 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 = 16/31/52 ms
R2#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 = 44/68/96 ms
可以看到,直连连通没有问题。
3、部署RIPv2路由协议,使得不同分支之间能够相互通信,配置如下:
R1(config)#router rip
R1(config-router)#version 2
R1(config-router)#no auto-summary
R1(config-router)#network 1.0.0.0
R1(config-router)#network 192.168.1.0
R1(config-router)#exit
R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#no auto-summary
R2(config-router)#network 2.0.0.0
R2(config-router)#network 192.168.1.0
R2(config-router)#exit
R3(config)#router rip
R3(config-router)#version 2
R3(config-router)#no auto-summary
R3(config-router)#network 3.0.0.0
R3(config-router)#network 192.168.1.0
R3(config-router)#exit
查看路由表,如下:
R1#show ip route rip
R
R
R2#show ip route rip
R
R
R3#show ip route rip
R
R
可以看到,全局路由信息已经同步,测试连通性,如下:
R1#ping 2.2.2.2 source 1.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
Packet sent with a source address of 1.1.1.1
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 16/52/80 ms
R1#ping 3.3.3.3 source 1.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:
Packet sent with a source address of 1.1.1.1
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 16/25/36 ms
R2#ping 3.3.3.3 source 2.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:
Packet sent with a source address of 2.2.2.2
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 24/52/84 ms
测试成功,说明在帧中继上部署RIPv2可以实现不同分支互联。但是需要提醒一点,默认情况下,运行RIPv2时,接口下关闭水平分割,如下:
R1#show ip interface s0/0
Serial0/0 is up, line protocol is up
……
若水平分割开启,则分支之间的路由信息学习会出现问题,在之后的实验中有解答。此实验完成。
