2 使用RIP协议处理不连续的子网和VLSM _云知道

监测清单5-2使用RIP协议处理VLSM和配置被动接口
第1段：RIPv1配置下的路由表
R3#sh ip route rip
172.16.0.0/30 is subnetted, 3 subnets
R　172.16.123.0 [120/1] via l72.16.123.5,00:00:12,Serial0
[120/1] via l72.16.123.9,00:00:12,Serial1
第2段：配置RIPv2和no summary
R3#conft
Enter configuration commands, one per line. End with CNTL/Z.
R3(config)#router rip
R3(config-router)#ver 2
R3 (config-router)#no auto-summary
Term_Server>2
[Resuming connection 2 to R2 ... ]
R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#router rip
R2(config-router)#ver 2
R2(config-router)#no auto-summary
Term_Server> 1
[Resuming connection 1 to R1 ... ]
R1#conft
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#router rip
R1(config-router)#ver 2
R1 (config-router)#no auto-summary
R1(config-rotuer)#end
R1#
R1#sh ip prot
Routing Protocol is "rip"
　Sending updates every 30 seconds, next due in 5 seconds
　Invalid after 180 seconds, hold down 180, flushed after 240
　Outgoing update filter list for all interfaces is
　Incoming update filter list for all interfaces is
Redistributing: rip
Default version control: send version 2, receive version 2
　Interface　Send　Recv　Triigered RIP　Key-chain
　Ethemet0 2　2
　Serial0　2　2
　Serial1　2　2
Automatic network summarization is not in effect

R1#sh ip route rip
172.16.0.0/30 is subnetted, 3 subnets
R　172.16.123.8 [120/1] via 172.16.123.2, 00:00:06, Serial0

172.18.0.0/16 is variably subnetted, 3 subnets, 2 masks
R　172.18,2,0/28 [120/1] via 172.16.123.2,00:00:06,SerialO
R　172.18J.O/24 [120/1] via 172.16.123.6, 00:00:22, Serial1
第3段：配置 passive interface
