Confusing about auto-RP

Hey mates,
I am having doubts about using auto-RP. I know that is necessary to enable dense-mode to announce “”. But I would like this:
All interfaces must be configured in sparse-dense mode?
Can I use loopback interface to tierbreak?
Thanks in advance!

Hello Alfredo

Take a look at Rene’s lesson on auto-RP here:

Once you go over that, if you have any specific questions, just let us know.

I hope this has been helpful!
