在此处输入图像描述我无法识别错误或我在此网络上的配置中缺少什么，如果你们中的任何人愿意检查它，这是链接PacketTracerFile 我无法从任何 PC ping 到路由器，也无法从任何交换机到任何路由器的用户名和密码对于所有设备都是相同的。用户名：亚当密码：1234

好的，您的问题是您尝试在路由器上进行路由，并且您在路由器上配置了 VLAN 接口，但您没有将 VLAN 从分布交换机中继到路由器：

interface GigabitEthernet0/1
 switchport access vlan 99
 switchport mode access
!

路由器的链接应该是这样的：

interface GigabitEthernet0/1
 description Connection to Router0 GigabitEthernet0/0
 switchport trunk encapsulation dot1Q ! some switches don't want this, but it is required for some
 switchport mode trunk
!

这会将所有 VLAN 中继到路由器，以便数据包可以从一个 VLAN 路由到另一个 VLAN。

此外，在您的交换机上，由于您在路由器上进行路由，它们将是第 2 层交换机，因此您需要删除除用于交换机管理的 SVI 之外的所有 SVI：

no interface Vlan10
!
no interface Vlan20
!
no interface Vlan30
!
no interface Vlan40
!
no interface Vlan50
!

如果您在一个 VLAN 上有 DHCP 服务器，则需要在所有其他 VLAN 上安装 DHCP 中继。这应该在路由器 VLAN 接口上完成：

ip helper-address <dhcp server address>

首先，我认为这是一个考试而不是问题，IPs vlsm 方案和生成树配置就是证明，无论如何。

1- 路由器和分布 SW 之间的链路必须配置为中继链路。

2- PC的网关必须配置相同的接口VLAN的IP

3- 对于上面的小型拓扑，最好将分布 SW 配置为 VLAN 的根交换机。

4 为所有 SW 1,2 和 3 配置默认网关到分发 SW。

5- 将以太通道重新配置为 LACP 或 PAGP。
