关于VLAN间互通问题,各位老大进来帮忙啊
[table=98%][tr][td]小弟买了个1802路由器,自带8个交换机口,可直接配置VLAN,我配置了两个DHCP地址池,动态给两个VLAN分配IP地址,分别为:vlan1 192.168.18.0 /24 vlan2 192.168.19.0 /24,每个vlan里电脑上网没问题,就是VLAN与VLAN之间无法PING通,请问如何做才能PING通啊?[/td][/tr][/table]interface FastEthernet0

end 没用过这款路由器，用show ip route看下路由表正确与否，另外你发的这个怎么有重复的，看的头晕 是的,Router#
Router#show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

Router# 路由表没什么问题
就是这种集成交换机的路由器没玩过，要是三层交换机启用ip routing一般就可以互访了，要是路由器+二层交换机，那么设置一下单臂路由也就可以了，你这种没见过不知道要设置什么 可是奇怪了,vlan2里面有台打印机,在VLAN1里的电脑却可以PING通,但是PING不通VLAN2里其它电脑, 有点奇怪~ 我发的配接口配置,请大家看看,是什么原因

--More-- 命令打错了 哪里错了啊,说明白些啊,哥们 貌似你只是划分了vlan，如果vlan之间互放还需要做其他的设置吧
具体不是很清楚 - - 同样学习中
FA口
我觉得你的FA口，应该按子网的方式来划为几个口，每一个口各设一个IP做为每个VLAN的网关，然后再写IP ROUTE 。。。的命令做路由页:
