If this multicast router +responds, the version number and a list of their neighboring multicast +router addresses is part of that response. If the responding router +has a recent multicast version number, then +.Nm mrinfo +requests additional information such as metrics, thresholds, and flags +from the multicast router. Once the specified multicast router +responds, the configuration is displayed to the standard output. +.Pp +The +.Nm +program accepts the following options: +.Bl -tag -width XXXdebuglevel +.It Fl d Ar debuglevel +This option sets the debug level to +.Ar debuglevel . +When the debug level is greater than the default value of 0, addition +debugging messages are printed.
