PC如何能PING通R1、R2以及与R2下的PC通信

baby063

拓扑

拓扑如图  可能会看不清楚，附件内有实验

目前情况，跟由与路由之间不通

R1与R2 下的PC 不能与路由通信

路由下的PC也不能互相通信

PC可 PING通三层交换机   三层交换机可PING通路由内网地址与外网地址

目的：
使两台路由之间能互相通信，R1下的PC能与R2下的PC通信

部份配置应该是错的，大神指导，感谢！！

配置如下：

三层交换机没开VLAN间路由。
左边路由器和右边路由器背后的网络都有192.168.1.0/24网段，这样的编址你让路由器遇到去这个网段的数据包，到底往哪走。
还有你每个设备都写默认路由，你真的知道数据包会按你的想法去走吗？
遇到网不通，就多用用ping、traceroute去看看数据包的走向。
在路由器上show ip route去看看路由表，到底需要打通的网段有没有加到路由表，如果加入了，下一跳都是指到哪里。
