I've been doing practice labs for three years now and just found the
multicast commands of mstat, mrinfo, and mtrace. This gets depressing
at times. On a daily basis I'll mistype a command and find a new
command I've never thought about before.
Thought I have seen mtrace before, just about forgot about it.
Any idea what packet mtrace uses? I can see the requirement now, apply
an access list and don't block mtrace traffic :)
R7#mtrace 136.10.1.1
Type escape sequence to abort.
Mtrace from 136.10.1.1 to 136.10.56.7 via RPF
From source (?) to destination (?)
