通过vlan+静态路由配置路由

我在配置网络时遇到问题。我在交换机之间创建了 VLAN：5、6、9 和 10。VLAN 9 是本机 VLAN。PC1 在 VLAN 5 中，PC0 在 VLAN 6 中。我配置了 R1，使其能够通过不同的 VLAN 进行通信（从 PC0 到 PC1 的 ping 操作正常）。现在我想从 PC1 ping R3 se0/2 接口，但没有响应。以下是我的配置文件：

如何更改我的网络配置以便能够从 PC0/PC1 ping 到 172.16.1.2 或 172.16.1.1？

答案1

我无法添加评论，但据我所知，您没有从 PC0/PC1 到达 R3 的路线。

您可以从 PC0 到达 PC1，因为它们在某种程度上连接到同一个网络，即使连接到不同的 VLAN。您需要在整个网络中构建一个路由表，以便您的 PC 可以到达 R2/R3。

您需要添加的基本路由是将 172.16.1.0/24 指向 R2 的内部 IP 地址。
