网络工程 - 在带有路由器的光纤 SFP 交换机中设置 VLAN - 吾爱随笔录

美好的一天，我正在模拟如下设置：

配置如下：

3 个交换机在 TRUNK 模式下与光纤相连。
PC0 加入 VLAN 20 (192.168.2.55/24) 中交换机的千兆端口，网关 192.168.2.254
PC1 加入 VLAN 10 (192.168.1.55/24) 中交换机的千兆端口，网关 192.168.1.254
使用 TRUNK 连接插入交换机的路由器，具有封装的端口 Fa0/0 的 ip 配置。

配置如下：

PC1

FastEthernet0 Connection:(default port)

   Link-local IPv6 Address.........: FE80::205:5EFF:FE9A:28D8
   IP Address......................: 192.168.1.55
   Subnet Mask.....................: 255.255.255.0
   Default Gateway.................: 192.168.1.254

PC2

FastEthernet0 Connection:(default port)

   Link-local IPv6 Address.........: FE80::290:CFF:FE04:E01C
   IP Address......................: 192.168.2.55
   Subnet Mask.....................: 255.255.255.0
   Default Gateway.................: 192.168.2.254

但。我无法从每台 PC ping 网关，我的意图是加入 2 台具有不同 VLAN 的 PC 以便能够相互通信。
