在三層交換機(jī)上配置RIP路由協(xié)議联四，以三層交換機(jī)代替路由器撑教。
通過RIP實(shí)現(xiàn)路由間通信
?方案
動(dòng)態(tài)路由協(xié)議配置靈活伟姐，路由器會(huì)發(fā)送自身的路由信息給其他路由器，同時(shí)也會(huì)接收其他路由器發(fā)來的路由信息建立自己的路由表鹿霸。這樣在路由器上就不必像靜態(tài)路由那樣為每個(gè)目標(biāo)地址都配置路由秆乳，因?yàn)槁酚善骺梢酝ㄟ^協(xié)議學(xué)習(xí)這些路由。網(wǎng)絡(luò)拓?fù)涓淖兏匾保酚尚畔⒁矔?huì)自動(dòng)更新，無需管理員干預(yù)珊肃。
步驟
1.按拓?fù)鋱D配置路由接口IP分別
2.在交換機(jī)上配置
Switch(config)#interface f0/6
Switch(config-if)#no switchport
Switch(config-if)#ip address 192.168.6.1 255.255.255.0
Switch(config-if)#no shutdown
3.分別在三層交換機(jī)和路由器上配置RIP路由協(xié)議
RIP路由協(xié)議在配置network時(shí)伦乔，只需要配置該路由器所直連的主類網(wǎng)絡(luò)评矩，不與該路由器直連的網(wǎng)絡(luò)不需要包含在network中阱飘。
RIP默認(rèn)工作在第一版本下，但是RIP-V1是有類路由協(xié)議蔗喂，而且通過廣播的方式進(jìn)行路由更新缰儿，無論是功能上還是效率上都有一些缺陷散址，這些缺陷RIP-V2可以彌補(bǔ)。在使用時(shí)建議采用RIP-V2而不是RIP-V1瞪浸。
tarenasw-3L(config)#router rip
tarenasw-3L(config-router)#version 2
tarenasw-3L(config-router)#no auto-summary
tarenasw-3L(config-router)#network 192.168.1.0
tarenasw-3L(config-router)#network 192.168.2.0
tarenasw-3L(config-router)#network 192.168.3.0
tarenasw-3L(config-router)#network 192.168.4.0
tarenasw-3L(config-router)#network 192.168.5.0
tarenasw-3L(config-router)#network 192.168.6.0
tarena-router(config)#router rip
tarena-router(config-router)#version 2
tarenasw-3L(config-router)#no auto-summary
tarena-router(config-router)#network 192.168.6.0
tarena-router(config-router)#network 192.168.7.0
4.分別在三層交換機(jī)和路由器上查看路由表
注意以R開頭的路由对蒲，這些路由表示通過RIP協(xié)議從其他運(yùn)行RIP的路由器學(xué)習(xí)過來的路由蹈矮。每條路由都寫明了目標(biāo)網(wǎng)絡(luò)鸣驱、下一跳IP地址以及從自己哪個(gè)端口發(fā)出去踊东。
