RE: How to Filter BSR Messages without the IP PIM BSR Command

 Hey thanks for the quick feedback,
I fully agree that the group I mentioned is the Auto-RP Discovery Group and
has no relation to BSR, but how come when we run BSR on any router , it
automatically joins the same group or is it that when ever we run Multicast
Group this message will be joined.

About leaking the link out, I would rather say that I tried many combination s
of ACL's and also the Multicast Filtering features but all ended up in vain.
I couldn't find anything specific on the DOC related to the filtration of BSR
messages.
The only thing I could find regarding the same was the IP PIM BSR Command,
which I want to keep aside at this moment !!
Can you please share link and uni-cast it to me in case if you know about such
link !!
thanks
