Why is this on r2's serial?
ip pim dr-priority 0
take it off for now, and please make every interface ip pim sparse-dense
mode
then, also, make sure we are neighbored up in pim
show ip pim neighbor
do the debugs on R3 again
at the very least you should be able to ping 224.2.2.2 from R2 regardless of
the helper-map

Go ahead and give me a ttl remap on R2's multicast helper-map command
(facing the broadcast)
So ttl 16
At the end of the map
Then lets do a #debug ip mpacket detail on R3

We'll help you doglover, don't worry...
Go ahead and give me a ip igmp join-group 224.2.2.2 on R3's F0/0 and a
Ip pim sparse-dense.
Now post back a "show ip mroute" on R2 and R3. I want to see what's in the
Multicast O.I.L.
Thanks,
Joe
(BTW: if you want to a webex to observe this work in my lab, we can, I
played this command for hours and hours and found several ways to get its
functionality without the helper-map)

Hello!
I am trying to simulate the forward of broadcast traffic into multicast
packets using the command "ip multicast helper-map", as the LAB8 of IE.
The network is the following:
R1 (e0/0) --- (f0/0) R2 (s0/1/0.1) <--FR--> (s0/1/0.1) R3 (fa0/0) ---
(fa0/0) R4
CONFIGS:

***R2 - Receive broadcast and send into multicast packets to 224.2.2.2

But When I try to see the multicast packets:
R2#debug ip mp
R2#debug ip mpacket
IP multicast packets debugging is on
R2#
R2#
R2#
Nothing happens at all...
R3:
R3#debug ip packet detail 111
IP packet debugging is on (detailed) for access list 111
R3#
Nothing happens too...

Anybody has any idea about what is wrong? Brian, could you help me?
I read everything that I found about this, but i really don't know what is
wrong...:
- Developing IP Multicast Networks - Chapter 16 - "Broadcast-Multicast
Traffic Conversion"
- IEWB - LAB 8 - Version 4
- "ip multicast helper-map" command:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cr/himc_r
/mlt_i1h.htm#wp1134745
Thanks for any help,
Zorby
