Agreed. AutoRP chooses the primary by highest RP -- IP address.
BSR chooses by priority first, and in the case of a tie then highest
RP-candidate -- IP address. I believe the RP is selected based on low
number priority, but the BSR is chosen based on high-number priority.
Unfortunately I believe one difference between a CCNP and a CCIE is not
only passing the test, but having some idea of the IOS and wht the
protocol inconsistencies are.
Would be nice to have high priority to be either a high or low number on
everything!

Look for another interface on R5 with a higher IP address than R6
loopback0,
and use it for R5 RP announcements.
