HCNA-28 RIP的路由引入
HCNA-28 RIP的路由引入先是接口地址配置：<Huawei>system-viewsysnamer4interfaceGigabitEthernet 0/0/0ipaddress 192.168.30.1 24 interfaceGigabitEthernet 0/0/1ipaddress 172.17.14.4 24 quitdisplayip interface brief <Huawei>system-viewsysnamer1interfaceGigabitEthernet 0/0/0ipaddress 172.17.14.1 24 interface GigabitEthernet 0/0/1ipaddress 172.16.12.1 24 interfaceGigabitEthernet 0/0/2ipaddress 172.16.13.1 24 quitdisplayip interface brief <Huawei>system-viewsysnamer2interfaceGigabitEthernet 0/0/0ipaddress 172.16.12.2 24 interfaceGigabitEthernet 0/0/1ipaddress 192.168.20.1 24 quitdisplayip interface brief <Huawei>system-viewsysnamer3interfaceGigabitEthernet 0/0/0ipaddress 172.16.13.3 24 interfaceGigabitEthernet 0/0/1ipaddress 192.168.30.1 24 quitdisplayip interface brief然后搭建B公司RIP网络rip1undosummary version 2network172.16.0.0quit rip1undosummary version2network172.16.0.0network 192.168.20.0quit rip1undosummaryversion2network172.16.0.0 network 192.168.30.0quit对R2GE 0/0/1接口抓包此时财务部PC会收到对自己没有任何用处的RIPv2报文，因为只要使用network命令通告财务部所在网段后，R2的GE0/0/0就会收发RIP协议报文，不管对端口设备是否利用。为了让财务PC不接收这些无用RIP更新报文，可以在R2的RIP进程中不使用network命令通告网段，而采用引入直连路由的方式来代替，把财务的网段当成外部路由发布到公司RIP网络中。 rip1undonetwork 192.168.20.0//先取消宣告参与网段import-routedirect//引入直连路由查看R1的路由表<r1>display ip routing-tableRouteFlags: R - relay, D - download to fib------------------------------------------------------------------------------RoutingTables: Public Destinations : 15 Routes : 15 Destination/Mask ProtoPreCost Flags NextHop Interface…… 192.168.20.0/24RIP 100 1 D 172.16.12.2 GigabitEthernet0/0/1192.168.30.0/24RIP 100 1 D 172.16.13.3 GigabitEthernet……配置引入路由后，R1的路由表同样学习到了192.168.20.0网段。此时再回到R2的GE 0/0/1接口上抓包，看看会不会再有RIP的更新报文。没有再出现RIPv2的更新报文了。如果需要研发部也与财务一样，相同的操作方法即可。最后再让A公司与B公司网络互通：R1做静态路由连接R4，然后R4配置默认路由访问R1iproute-static192.168.40.0 24 172.17.14.4//配置静态路由 下一跳地址 iproute-static0.0.0.0 0.0.0.0 172.17.14.1//配置默认路由下面使用PC1Ping PC3Ping192.168.40.100: 32 data bytes, Press Ctrl_C to breakRequesttimeout!Requesttimeout!Requesttimeout!Requesttimeout!Requesttimeout!---192.168.40.100 ping statistics ---5 packet(s) transmitted0 packet(s) received100.00% packet loss重要的事情来了,此时A与B之间的网络仍然不可互通，这是因为B边的RIP网络无法识别A的外界非RIP协议网络，需要配置路由引入后才可互通！！下面在R1上做路由引入import-routestatic//配置引入静态路由此时再使用PC1Ping PC3PC>ping192.168.40.100Ping192.168.40.100: 32 data bytes, Press Ctrl_C to breakRequesttimeout!From192.168.40.100: bytes=32 seq=2 ttl=125 time=78 msFrom192.168.40.100: bytes=32 seq=3 ttl=125 time=79 msFrom192.168.40.100: bytes=32 seq=4 ttl=125 time=78 msFrom192.168.40.100: bytes=32 seq=5 ttl=125 time=78 ms---192.168.40.100 ping statistics ---5 packet(s) transmitted4 packet(s) received20.00% packet lossround-trip min/avg/max = 0/78/79 ms完成通信工作。
