16 |PROGRAM| is a program to initiate multicast traceroute, or "mtrace", queries.
18 The initial version of the program requires multicast source IP address and
19 initiates a weak traceroute across the network. This tests whether the
20 interfaces towards the source are multicast enabled. The first query sent is a
21 full query, capable of crossing the network all the way to the source. If this
22 fails, hop-by-hop queries are initiated.
24 Hop-by-hop queries start by requesting only a response from the nearest router.
25 Following that, next query is extended to the next two routers, and so on...
26 until a set of routers is tested for connectivity.
