you should use a dvmrp tunnels.
take a look at this link

Subject: Multicasting's Question !!!
Hi..Everyone
I have a weak point in Multicasting.
So i was confused by this question..
How can i solve this multicasting problem ??
Thanks..
--------
Diagram
---------
(e0 1.1.1.1)-R1-(s0 2.2.2.1)-FR-(s1.1 2.2.2.2)-R3-(e0 3.3.3.1)-(e0 4.4.4.1)-R4
|
FR
|
(s0 2.2.2.3)
|
R2
-R1'S0,R2'S0 & R3's S1.1 are covered with a F/R
& in same subnets
-R3 is a HUB, R1 & R2 are Spokes
-R3's S1.1 is a multipoint-subinterface
-The all interfaces of R1,R2,R3 & R4 are in a OSPF-Dpmain
----------
Question
----------
A> Enable PIM-DM on R1,R2 & R3's F/R-interface,R1's E0 & R4's E0
B> Do not enable multicasting on any other router interface
R3 & R4 shall accept DVMRP reports only from 100.100.100.1
C> Make sure that R3 can transmit DVMRP route reports to the FR-Network
& the network that is on the E0 of R5, but no other routes
=>I don't know the meaning of this question..!!
-----------
My Answer
-----------
A> => A general PIM-DM configuration..
=> Why isn't the e0 of R3 in PIM-DM ???
