Hi..Ozgur..
Thanks for your kind reply..
After reading the tech-note, i solveed Question-C> like the below..
This is correct ?
and i have a question to you..
-in Doc-CD,
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fipr
_c/ipcpt3/1cfdvmrp.htm#1001000
there is a comment like this "You cannot configure a DVMRP tunnel between two
routers."
=> This means that i must configure a dvmrp-tunnel only one side router
that
is not running DVMRP ??
=>Then If it's right , Must i configure a
DVMRP-Tunnel only one router
between R1 & R3..?
=> I think R3 is considered as running DVMRP,
so, I configure a DVMRP-Tunnel only on R1 !!!!!
=> Is my solution Correct ????

you should use a dvmrp tunnels. take a look at this link http://www.cisco.com/warp/public/cc/techno/protocol/ipmu/prodlit/dvmrp_an.htm

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 ???
