路由重发布

Posted 2021-01-26

1、 配置地址
2、 配置ospf路由
3、 配置RIP
4、 R3上配置静态路由目标网络192.168.6.0 下一跳192.168.4.2
5、 配置OSPF重发布到RIP 中
6、 配置RIP重分布到OSPF中
7、 重发布直连路由到RIP　和ospf　中去
8、 重发布静态路由到RIP和OSPF中去
9、 重发布默认路由到RIP 和OSPF中去

基本配置

在路由重发布之前要查看各路由器的路由条目

R2上的路由信息
C 192.168.1.0/24 is directly connected, FastEthernet0/0
C 192.168.2.0/24 is directly connected, FastEthernet1/0
R2#

R4上的路由信息
R4#show ip route
C 192.168.3.0/24 is directly connected, FastEthernet0/0

在R3上进行路由重发布
R3(config)#router rip
R3(config-router)#redistribute ospf 1 metric 2 发布OSPF到RIP
R3(config-router)#redistribute connected 发布直连路由
R3(config-router)#redistribute static metric 5 发布静态路由
R3(config-router)#default-information originate 发布默认路由
R3(config-router)#exit
R3(config)#
R3(config)#router ospf 1
R3(config-router)#redistribute rip subnets 发布RIP到OSPF
R3(config-router)#redistribute connected subnets发布直连路由
R3(config-router)#redistribute static subnets发布静态路由
R3(config-router)#default-information originate always发布默认路由
