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 recent multicast +version number, then +.Nm +requests additional information such as metrics, thresholds, and flags from the +multicast router. For each new occurrence of neighboring multicast router in +the reply and provided the flooding option has been selected, then +.Nm +asks each of this multicast router for a list of neighbors. This search +for unique routers will continue until no new neighboring multicast routers +are reported. +.Pp +The options supported by +.Nm +are as follows: +.Bl -tag -width XXXdebuglevel +.It Fl d Ar debuglevel +This sets the debug level to +.Ar debuglevel . +When the debug level is greater than the default value of 0, +additional debugging messages are printed. Regardless of the debug +level, an error condition, will always write an error message and will +cause +.I map-mbone +to terminate. +Non-zero debug levels have the following effects: +.Bl -tag -width "level 3" +.It level 1 +packet warnings are printed to stderr. +.It level 2 +all level 1 messages plus notifications down networks are printed to stderr. +.It level 3 +all level 2 messages plus notifications of all packet +timeouts are printed to stderr. +.El +.It Fl f +This option enables flooding. Flooding allows +.Nm +to perform recursive search +of neighboring multicast routers and is enabled by default when an +initial +.Ar router +is not specified. +.It Fl g +This option enables graphing in GraphEd format. +.It Fl n +This option disables the DNS lookup for the multicast routers' names. +.It Fl r Ar retries +This options sets the neighbor query retry limit to +.Ar retries . +The default is one retry. +.It Fl t Ar timeout +This option sets the number of seconds to wait for a neighbor query +reply before retrying.
