Matthew,
If a situation calls for sparse mode, you know that you are either going to
need autorp or bsr. If it further requires you to use an industry standard
method, then bsr would be the direction you are headed. However, there is an
understanding of how autorp and bsr traffic is delivered. Autorp requires
dense mode operation, thus if you cannot use sparse-dense and have only
sparse as an option, the 'ip pim autorp listener' global commmand will be
necessary. This will allow for your 224.0.1.39 and .40 messages to be sent
out in dense mode over sparse mode operational interfaces. There are
caveates to this in an nbma environment, with outgoing interface-list and
such.
Give a look at this thread between Nick and Brian McGahan.

It gives some great details to remember and help spot the issue for when to
use autorp or bsr when the only information you have is use sparse-mode.
Regards,
Wayne
P.s. thanks again Brian

Subject: Multicast - comparison between AUTO-RP & BSR
Hi Group,
Can someone explain me what are the factors to check before choosing AUTO-RP
or BSR in multicast?
It will be good if someone has a link for the comparison between AUTO-RP
BSR
Thank you in advance.
