Yep! So, either you can modify/create IP addresses to make this occur,
or just choose a different interface on the router to make this happen.
Either way works, but your scenario make force you to use one option
over another.

So if you want one to be primary, you make sure it's source interface
has a higher IP address than the backup? (assuming they are advertising
the same
prefixes)

For RP conflict resolution, longest-match prefix is used, if a tie then
highest IP address. For mapping agents, highest IP address is speaker.
So, if you have any RP-announce-filters or anything, you'll want to make
sure they are the same on all mapping agents.

Multicast question I can't find an answer to.
Let's say you have sparse-dense mode turned on and you configure two
auto-rp's. How do you make one preferred over another
(primary/secondary)?
