ccna vlan间路由 疑问

cglovelee

还是ping 不通啊。。。如果把sw2连上的话，单臂路由好像也不能成功了。把sw1和sw2之间改成交叉线也不行，，，求高手解啊。。。

思路：r1上：分别有三个子接口，并分别封装协议、配置IP地址
sw1上：创建vlan 2和vlan 3,并指定端口
sw2上：创建vlan 4并指定端口
sw1上：f0/24和f0/23设置成trunk模式
sw2上：f0/24设置成trunk模式
我用的是PT5.3的，应该和版本没什么关系

r1上的命令：

首先 把路由器f0/0“no shutdown”
其次 单臂路由配置时 vlan ID 与封装 ID一致
