Rajib,
you will only need it on the final segment of the last hop router ( the receiver's segment ).
this link is good to read :
http://www.cisco.com/univercd/cc/td/doc/cisintwk/ics/cs006.htm
I tested it several weeks ago, and noticed the DocCD is incorrect.
btw, IE has similar task like this on Lab 8.
Rgds,
Thomwin

I think if you put ip directed-broadcast under s1/1 and e1/1 on R2 it should still work.
Please correct me if I am wrong
Thanks

Thanks Brian,
I dont't have chance to lab it up. :(
I just wonder that the doc-cd could be incorrect.
Is somebody from Cisco aware about it ?
best regards

Yes, the documentation is incorrect. Try it out and you will see. You can use the Service Assurance Agent (rtr) to generate a broadcast UDP for testing it. This is also demonstrated in the IEWB-RS Volume I Solutions Guide if you have access to it.

Subject: RE: ip multicast helper-map - position of ip directed-broadcast command ??
Thanks Brian,
I agree with you that it should be put on the bcast domain interface
Well, it is different according to
http://127.0.0.1:8089/cc/td/doc/product/software/ios122/122cgcr/fipr_c/ipcpt3/1cfmulti.htm#wp1003511
that the ip directed-command is put on s1/1 R2
any thought ?

Hino,
It need to go on E1/1 of R2. This is where the directed
broadcast is being sent to
