NAME

6       mtracebis - a multicast trace client

SYNOPSIS

9       mtracebis [-h] [-v]
10
11       mtracebis <multicast source> [<multicast group>]

DESCRIPTION

14       mtracebis   is  a  program  for  initiating  multicast  traceroute,  or
15       "mtrace", queries.
16
17       It can initiate two types of mtrace queries: weak and group.
18
19       Weak tests whether the interfaces  towards  the  source  are  multicast
20       enabled  and  is  initiated  by  supplying  only  the  multicast source
21       address.
22
23       Group tests whether there is multicast routing protocol state for  par‐
24       ticular  multicast group and is initiated by supplying mutlicast source
25       and group.
26
27       The first query sent is a full query, capable of crossing  the  network
28       all the way to the source. If this fails, hop-by-hop queries are initi‐
29       ated.
30
31       Hop-by-hop queries start by requesting only a response from the nearest
32       router.   Following  that,  next  query  is  extended  to  the next two
33       routers, and so on...  until a set of routers is tested for  connectiv‐
34       ity.
