Yes! The icannotreach statement can be used to filter also, but read the
requirements carefully if it is a test question.

> This command can be entered at any time. It causes a capabilities exchange

peers

avoid

configure

will

NetBIOS

connections
> will be limited to those with a destination name that is specified in the
> list.
>
> In the default case (where the remote keyword is not specified), a local
