努力使我的PC ping通路由器的子接口

Question

嗨，这是我有史以来第一个问题，希望我能得到答案。

我正在为大学项目创建此网络。 到目前为止，我已经在总部建立了4个VLAN，在另一个办公室建立了一个VLAN。 有VLAN 11,22,33,44,55。 我已经在总公司设置了中继线，并在整个网络上进行了eigrp路由。

当我尝试从主网络ping到另一个网络时，它只是说目标主机不可达，并停留在vlan ip或子接口ip。

这是我设备的配置 R1

如果您还有其他需要，请告诉我。 另外还要注意eigrp路由正在工作，并且正在填充路由表，它只是不会让WAN认为任何事情。

更新：发现我可以从较小的网络ping较大的网络上的所有PC。必须很容易解决！也许子接口和VLAN的IP是相同的？

谢谢！
