CCNA实验求助！有图有真相！

目的是让所有PC全网全通
VLAN，OSPF，单臂路由都弄过了，为什么左边的PC PING 不通右边的PC，研究了半天了。。。

问题是你两个路由之间的路由是怎么做的?

请问，你做ospf宣告的是什么网段?

跨路由器的话左边和右边不能在同一个网段，你左边的路由器直连192.168.1.0/24和192.168.2.0/24；右边的路由器也是直连192.168.1.0/24和192.168.2.0/24；路由器不知道往哪里走了

ziyouhaiyang

建议：把右边的主机划分子网，和左边不要在同一个网段就可以

原来如此！受教了~准备再在这个基础上练ACL和NAT

showlink

IP划分错了
右边的与左边的1.0和2.0重叠了
左边去往右边的包会被路由直接丢回来

把右边划为5.0和6.0就行了
