Terry -
Sorry for the confusion on the first part....you are correct. I meant
to say that you need the sparse in their (either spare or sparse-dense).
Now, I believe that the BSR (IETF standard) requires sparse mode only.
Correct?
Here is the link for the dm-fallback....

Subject: Re: Multicast - No ip pim dm-fallback vs. Sink RP
Wow - this is an intersting post to me.
First of all - we can use Auto-RP and sparse-mode together. We are not
required to use sparse-dense just because we are using Auto-RP. I just
wanted to make that clear before I got myself even more confused.....
Now - if we are told we have to use sparse-dense - and we are told to
NEVER go into dense mode.......this is interesting.....I am thinking
there are several options.....but.......I have never heard of the
command "no ip pim dm-fallback" you mention here. Can you send me a link
to that command?

If there is a requirement that requires you to use Auto-RP, which means
using sparse-dense mode. And, another requirement to insure that you
never go into dense mode.....is it more correct to:
1. Use the command - "no ip pim dm-fallback"
Or,
2. Use the "sink RP" configuration that cisco details in the
following white-paper.....
