帧中继hub and spoke点到点子接口的配置
实验拓扑图:
实验过程
1.R1的配置
Router>en Router#config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#no ip domain-lookup Router(config)#line console 0 Router(config-line)#no exec-timeout Router(config-line)#loggin syn Router(config-line)#exit Router(config)#host R1 R1(config)#interface s0/0 R1(config-if)#no shut R1(config-if)#encapsulation frame-relay //封装帧中继 R1(config-if)#no frame-relay inverse-arp //关闭反向ARP R1(config-if)#exit R1(config)#interface s0/0.1 point-to-point R1(config-subif)#frame-relay interface-dlci 102 //配置s0/0.1的dlci号 R1(config-fr-dlci)#ip add 172.16.0.1 255.255.255.0 R1(config-subif)#exit R1(config)#interface s0/0.2 point-to-point R1(config-subif)#frame-relay interface-dlci 103 R1(config-fr-dlci)#ip add 192.168.0.1 255.255.255.0 R1(config-subif)#end |
2.R2的配置
Router>en Router#config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#no ip domain-lookup Router(config)#line console 0 Router(config-line)#no exec-timeout Router(config-line)#loggin syn Router(config-line)#exit Router(config)#host R2 R2(config)#interface s0/0 R2(config-if)#no shut R2(config-if)#ip add 172.16.0.2 255.255.255.0 R2(config-if)#encapsulation frame-relay //封装帧中继 R2(config-if)#frame-relay map ip 172.168.0.1 201 br //配置映射表 R2(config-if)#no frame-relay inverse-arp //关闭反向ARP R2(config-if)#end |
3.R3的配置
Router>en Router#config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#no ip domain-lookup Router(config)#line console 0 Router(config-line)#no exec-timeout Router(config-line)#loggin syn Router(config-line)#exit Router(config)#host R3 R3(config)#interface s0/0 R3(config-if)#no shut R3(config-if)#encapsulation frame-relay R3(config-if)#no frame-relay inverse-arp R3(config-if)#frame-relay map ip 192.168.0.1 301 br R3(config-if)#ip add 192.168.0.2 255.255.255.0 R3(config-if)#end |
4.查看帧中继map表
R1#show frame-relay map Serial0/0.2 (up): point-to-point dlci, dlci 103(0x67,0x1870), broadcast status defined, active Serial0/0.1 (up): point-to-point dlci, dlci 102(0x66,0x1860), broadcast status defined, active |
5.测试连通性
R2#ping 172.16.0.1
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 172.16.0.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 8/36/84 ms R3#ping 192.168.0.1
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.0.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 20/52/104 ms R2#show frame-relay map Serial0/0 (up): ip 172.168.0.1 dlci 201(0xC9,0x3090), static, broadcast, CISCO, status defined, active R2#ping 192.168.0.2
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.0.2, timeout is 2 seconds: ..... //因为R2没有到R3的映射,所以不通 Success rate is 0 percent (0/5) |
6.配置R2到R3的静态映射
R2(config)#interface s0/0 R2(config-if)#frame-relay map ip 192.168.0.2 201 br R2(config-if)#end R3(config)#interface s0/0 R3(config-if)#frame-relay map ip 172.16.0.2 301 br R3(config-if)#end |
7.测试R1和R2连通性
R2#show frame-relay map Serial0/0 (up): ip 172.168.0.1 dlci 201(0xC9,0x3090), static, broadcast, CISCO, status defined, active Serial0/0 (up): ip 192.168.0.2 dlci 201(0xC9,0x3090), static, broadcast, CISCO, status defined, active R2#ping 192.168.0.2
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.0.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 8/48/116 ms |
