Jason,
Your RP ( R4 ) need to know that it is the RP. so the command "ip pim rp
add" is requiered in R4. also the multucast ping work because you are
configuring pim sparse-dense-mode. so when R4 can't use the sparse mode for
multicast routing because it does'nt know the RP it use the dense mode.

Objet : Multicast - a bit clueless!
Ok, I am now into multicasting, and I am having trouble confirming my
work. This is IPE Section 17 (for anyone who has it). Here is the
topo:
/-----R4
R1-R2
| \
| \
R5---R6
| /
| /
R7
|
R8
Routers 1and 2 are connected via Ethernet segment. R5,6,7 are as well
(different segment).
Problem 1
This error message appears on R4:
r4# %PIM-6-INVALID_RP_JOIN: Received (*, 224.44.44.44) Join from
150.50.24.2 for invalid RP 150.50.24.4
Also, when I ping 224.44.44.44 from R2, it looks as though R5 is
responding:
r2#ping
