boson小学实验，大家来帮忙
boson6.0环境
[SW3550] 设置
vlan 10 (1-6 e口) (9.114.65.254 255.255.255.0)
vlan 20(7-12 e口) (172.29.47.254 255.255.255.0)
其中2口 插 PC1：9.114.65.2 255.255.255.0 9.114.65.254
其中7口 插 PC2：172.29.47.2 255.255.255.0 172.29.47.254
问题：PC1 ping 网关9.114.65.254 竟然不通···为什么啊··已经开启 ip routing
[我的目标是 PC1 ping通 PC2 但现在 PC竟然连网关都不通]
以下是sw3550 配置

Switch#
[解决办法]
掩码错误。实际上讲，没有这样的掩码长度。
[解决办法]
这个应该是你的模拟器的bug
