First, could you confirm that you have enabled multicast routing and
PIM-SM in your kernel as specified in the user manual (Section
13.3.1).

If yes, could you enable the PIM-SM traceoptions in your config
file:

protocols {
    pimsm4 {
    ...
	traceoptions {
	    flag all {
		disable: false
	    }
	}
    }
}

For completeness, you may want to enable the traceoptions for mfea4
and igmp.

Some of the log messages should show the MFC entries that are added
to the kernel. If there is no obvious error, please send me your
complete log output and I will have a look at it (you don't need to
CC the list).
