       mtracebis is a program for initiating multicast traceroute, or "mtrace", queries.

       It can initiate two types of mtrace queries: weak and group.

       Weak  tests whether the interfaces towards the source are multicast enabled and is initiated by supplying
       only the multicast source address.

       Group tests whether there is multicast routing protocol state  for  particular  multicast  group  and  is
       initiated by supplying mutlicast source and group.

       The  first query sent is a full query, capable of crossing the network all the way to the source. If this
       fails, hop-by-hop queries are initiated.

       Hop-by-hop queries start by requesting only a response from the nearest  router.   Following  that,  next
       query  is  extended  to  the  next  two  routers,  and  so  on...   until  a set of routers is tested for
       connectivity.

       The daemon may log to standard output, to a VTY, to a log file, or through syslog to the system logs. FRR
       supports many debugging options, see the Info file, web docs or source for details.
