RE: Errors in the DOC-CD for Multicast Intermediate Helper

You mean the new documentation way in-line with current IOS where we place

This

 ip multicast helper-map 239.254.2.5 126.1.28.255 105

on the interface facing the multicast , not sending the final "back to lan
broadcast" ?

One cool thing-

By default IOS sends "directed broadcasts" to 255.255.255.255 (even if the
command above specified "126.1.28.255" as the broadcast to address). If you
*really* want to send the broadcast to the subnet broadcast (directed)
address you need to put ip broadcast-address 126.1.28.255 on the out going
interface...

Lab it up sometime, check it out...

Subject: Errors in the DOC-CD for Multicast Intermediate Helper

Hello all!

I am too tired right now to investigate so I am looking for immediate
assistance from the group...it would appear that Cisco has finally
corrected the Multicast Helper example in the DOC-CD.

Can someone please confirm....
