Yes, this is a known problem.
After the cable is reconnected to the interface you can do the
following: disable then enable (inside xorpsh) the affected
interface. You need to disable and enable it in mfea4, igmp and
pimsm4. E.g.:

set protocols pimsm4 interface rl0 vif rl0 disable true
# commit
set protocols igmp interface rl0 vif rl0 disable true
# commit
set multicast mfea4 interface rl0 vif rl0 disable true
commit

set protocols pimsm4 interface rl0 vif rl0 disable false
# commit
set protocols igmp interface rl0 vif rl0 disable false
# commit
set multicast mfea4 interface rl0 vif rl0 disable false
commit

If this doesn't work, then you might need to use the commented-out
"commit" commands as well.

You need to add the register_vif to mfea4 before adding it to
pimsm4. E.g.

set plumbing mfea4 interface register_vif vif register_vif
# commit
set protocols pimsm4 interface register_vif vif register_vif
commit

Hope that helps,
