配置RIP V1 ,使PCA可以访问PCB:
[RTA]interface s6/0
ip address 11.1.1.1 24
interface g0/0
ip address 10.1.1.1 24
[RTB]interface s6/0
ip address 11.1.1.2 24
interface g0/0
ip address 12.1.1.1 24
PCA:10.1.1.2 255.255.255.0
PCB:12.1.1.2 255.255.255.0
配置RIP V1,让各网段连通:
[RTA]rip 1
network 10.1.1.0
network 11.1.1.0
[RTB]rip 1
network 11.1.1.0
network 12.1.1.0
此时RTA,RTB都学习到了路由信息,可以相互访问。但是RIP V1是自动汇总开启的无法关闭,不支持携带子网信息,所以获取的是汇总信息。并不能完全的反应正确网段的信息。
