帧中继(Frame Relay) 点到多点子接口实验.doc

帧中继（Frame Relay） 点到多点子接口实验拓朴图如图所示。使用Dynamips的帧中继交换机的net文件如下：autostart = Falselocalhost port = 7200 udp = 10000 workingdir = .workingdir3620 #不能用来插交换模块 image = J:c3620-i-mz.121-20.bin ram = 32 confreg = 0x2142 mmap = false idlepc = 0x60395fd0 exec_area = 32 slot0 = NM-1FE-TX slot1 = NM-4T ROUTER R1 model=3620 S1/0 = FR1 1 ROUTER R2 model=3620 S1/0 = FR1 2 ROUTER R3 model=3620 S1/0 = FR1 3 ROUTER R4 model=3620 S1/0 = FR1 4 FRSW FR1 1:102 = 2:201 1:103 = 3:301 1:104 = 4:401#注意：FR1的lmi类型是ANSI，所以各个路由器上要设置frame-relay lmi-type ansi 如果你不想使用Dy的帧中继交换机，可以使用路由器来模拟帧中继交换机，该net文件如下：autostart = Falselocalhost port = 7200 udp = 10000 workingdir = .workingdir3620 #不能用来插交换模块 image = J:c3620-i-mz.121-20.bin ram = 32 confreg = 0x2142 mmap = false idlepc = 0x60395fd0 exec_area = 32 slot0 = NM-1FE-TX slot1 = NM-4T router FR model=3620 S1/0 = R1 S1/0 S1/1 = R2 S1/0 S1/2 = R3 S1/0 S1/3 = R4 S1/0 router R1 model=3620 router R2 model=3620 router R3 model=3620 router R4 model=3620 配置过程命令如下：如果使用路由器来模拟帧中继交换机，帧中继交换机的配置如下：!对帧中继交换机的配置FR#enableFR#configure terminal FR(config)#frame-relay switching FR(config)#interface serial 1/0FR(config-if)#no shutdown FR(config-if)#encapsulation frame-relay FR(config-if)#frame-relay lmi-type ansi FR(config-if)#frame-relay intf-type dceFR(config-if)#frame-relay route 102 interface Serial1/1 201FR(config-if)#frame-relay route 103 interface Serial1/2 301FR(config-if)#frame-relay route 104 interface Serial1/3 401FR(config-if)#exitFR(config)#interface serial 1/1FR(config-if)#no shutdown FR(config-if)#encapsulation frame-relay FR(config-if)#frame-relay lmi-type ansi FR(config-if)#frame-relay intf-type dceFR(config-if)#frame-relay route 201 interface Serial1/0 102FR(config-if)#exitFR(config)#interface s1/2FR(config-if)#no shutdown FR(config-if)#encapsulation frame-relay FR(config-if)#frame-relay lmi-type ansi FR(config-if)#frame-relay intf-type dceFR(config-if)#frame-relay route 301 interface Serial1/0 103FR(config-if)#exitFR(config)#interface serial 1/3FR(config-if)#no shutdown FR(config-if)#encapsulation frame-relayFR(config-if)#frame-relay lmi-type ansi FR(config-if)#frame-relay intf-type dceFR(config-if)# frame-relay route 401 interface Serial1/0 104FR(config-if)#endFR#show frame-relay route !如果能够显示如下信息，说明帧中继交换机的交换表配置成功。Input Intf Input Dlci Output Intf Output Dlci StatusSerial1/0 102 Serial1/1 201 inactiveSerial1/0 103 Serial1/2 301 inactiveSerial1/0 104 Serial1/3 401 inactiveSerial1/1 201 Serial1/0 102 inactiveSerial1/2 301 Serial1/0 103 inactiveSerial1/3 401 Serial1/0 104 inactive!如果相邻路由器也启动且各个接口已经配置，则应该是显示如下信息Serial1/0 102 Serial1/1 201 activeSerial1/0 103 Serial1/2 301 activeSerial1/0 104 Serial1/3 401 activeSerial1/1 201 Serial1/0 102 activeSerial1/2 301 Serial1/0 103 activeSerial1/3 401 Serial1/0 104 activeFR#!也可以用下面的配置方法enableconfigure terminalframe-relay switchinginterface Serial1/0no ip addressencapsulation frame-relayno shutdownframe-relay lmi-type ansiframe-relay intf-type dceframe-relay route 102 interface Serial1/1 201frame-relay route 103 interface Serial1/2 301frame-relay route 104 interface Serial1/3 401!interface Serial1/1no ip addressencapsulation frame-relayno shutdownframe-relay lmi-type ansiframe-relay intf-type dceframe-relay route 201 interface Serial1/0 102!interface Serial1/2no ip addressencapsulation frame-relayno shutdownframe-relay lmi-type ansiframe-relay intf-type dceframe-relay route 301 interface Serial1/0 103!interface Serial1/3no ip addressencapsulation frame-relayno shutdownframe-relay lmi-type ansiframe-relay intf-type dceframe-relay route 401 interface Serial1/0 104!end!show frame-relay route!以下是各个路由器的配置!对R1的配置enableconfigure terminal! interface FastEthernet0/0ip address 10.1.1.1 255.255.255.0no shutdown!interface Serial1/0no ip addressno shutdownencapsulation frame-relayno frame-relay inverse-arpframe-relay lmi-type ansi!interface Serial1/0.2 point-to-pointip address 12.12.12.1 255.255.255.0frame-relay interface-dlci 102!interface Serial1/0.34 multipointip address 13.13.13.1 255.255.255.0no ip split-horizonframe-relay map ip 13.13.13.3 103 broadcastframe-relay map ip 13.13.13.4 104 broadcast!exit!router ripnetwork 10.0.0.0network 12.0.0.0network 13.0.0.0!end!对R2的配置enableconfigure terminal! interface FastEthernet0/0ip address 172.16.1.2 255.255.255.0no shutdown!interface Serial1/0ip address 12.12.12.2 255.255.255.0encapsulation frame-relayno shutdownframe-relay map ip 12.12.12.1 201 broadcastno frame-relay inverse-arpframe-relay lmi-type ansi!exit!router ripnetwork 172.16.1.0network 12.0.0.0!end!对R3的配置enableconfigure terminal! interface FastEthernet0/0ip address 192.168.1.3 255.255.255.0no shutdown!interface Serial1/0ip address 13.13.13.3 255.255.255.0encapsulation frame-relayno shutdownframe-relay map ip 13.13.13.1 301 broadcastno frame-relay inverse-arpframe-relay lmi-type ansi!exit!router ripnetwork 192.168.1.0network 13.0.0.0!end!对R4的配置enableconfigure terminal! interface FastEthernet0/0ip address 192.168.1.4 255.255.255.0
