本人目前在学习路由器,下面是一个单臂路由的实验,我该配的都配了 ,VLAN划的没错 ,DOT1Q封装,TRUNK链路都配了, a.b.c的网关配的1.4D,E.F的网关为 2.4为什么能ping通网关ping不到对端?目的全网通信,任意一点可以ping通,请告诉我所有命令,包括划分VLAN,满意追加100分,那些粘来的就不用了 ,

交换机和路由器连接线为直通线 路由器F0/0端口连接交换机1端口
配置F0/0.1 封装 encapsulation dot1q 2(VLAN号)
配置网关IP地址
F0/0.2封装VLAN3 encapsulation dot1q 3 也配置IP
其余电脑设置相对应的IP和网关就可以了 下面是路由器的配置命令 交换机只是简单创建VLAN 然后将端口指定为TRUNK或ACCESS 然后划分到VLAN下就可以了 VLAN不需要指定IP地址
interface FastEthernet0/0.1
encapsulation dot1Q 2
ip address 192.168.1.254 255.255.255.0
interface FastEthernet0/0.2
encapsulation dot1Q 3
ip address 192.168.2.254 255.255.255.0

第二，配置没问题。从图中可知，路由和交换机连接电缆，错了，用真通。
