Hi, Group,

I just grabed some configuration from cisco website as below, but just don't
know why broadcast key-word is issued because that would make it work as a
broadcast network. Even if there is no neighbor command, the network should
work. Your clarification is greatly appreciated.

Thanks,

Mac
