求助.单臂路由vlan1 Ping不通网关.
单臂路由的实验...划分vlan之后.两个不同vlan内的PC是可以Ping通的.
Vlan1已经设置了IP与网关.路由上也有封装.但是Ping不通交换机上的vlan 1.
请问为什么呢?

end 我刚刚做了一遍，是能够ping通的。你的配置
interface Ethernet0/0.1
encapsulation dot1Q 1 native
ip address 192.168.10.254 255.255.255.0
这个配置我没明白为什么要加这个，但是你给的VLAN1的管理IP是跟这个一个网段的，显然这样PC是无法管理SW1的，交换机的管理IP需要跟PC在同一个网段。

我这边还是不可以...ping不通..我说的是 PC Ping Vlan1 Ping不通哦
interface Ethernet0/0.1
encapsulation dot1Q 1 native
敲这个就是为了使PC访问处在不同网段的vlan 1
跟封装 10和20类似 我刚真正看懂你的意思，你是想建立三个子接口，我刚试了下，是能够成功做通的，你把PC划入你的vlan 10里面，就可以了！
interface FastEthernet1/0
switchport access vlan 10 回复 4# gechao890302
额.PC已经划进去了...两个不同Vlan内的PC也是通的..但是Ping不通Vlan 1的IP..你可以Ping通vlan1? 再检查一遍吧，我是可以ping vlan1的网关和SW1的管理IP的 我是想做远程管理交换机的实验... 回复 6# gechao890302
哦.你是用小凡模拟器吗? 不是啊，GNS3 回复 9# gechao890302
哦.明白了.非常感谢.......
