我有 VLAN10 和 VLAN20，我正在尝试在以下设置中使用相同 VLAN 的计算机之间进行通信：

我想从路由器应用封装，但它似乎无法识别相应的命令。报告如下：

R14(config)#int gig2/2
R14(config-if)#int gig2/2.10
               ^
% Invalid input detected at '^' marker.
    
R14(config-if)#exit
R14(config)#int gig2/1
R14(config-if)#int gig2/2.10
               ^
% Invalid input detected at '^' marker.
    
R14(config-if)#
R14#

这是路由器的运行配置：

R14#show running-config

不知道是否相关，但我已将交换机和路由器的 vlan 1 ip 地址调整为 192.168.10.1 。

为什么路由器无法识别此命令，我该如何解决？
