Thank you for the reply, I got it to work by enabling PIM-SM on R4's
loopback....I don't know why I need it there...it's just being a receiver
with the join command....I guess I am misunderstanding this a bit.
FYI, I joined a group on R4's serial connection to R2 and I can't reach that
group address, only the R4 loopback group.
