Tricky wording. The auto-rp groups will not run in sparse mode, but all
other groups that you have set up at the rp will run in sparse mode. If it
says Sparse mode only, you could argue that whatever group they ask you to
ping IS using sparse mode.
I am thinking that sparse mode auto-rp is failing across your tunnel path
because there is no join for the auto-rp groups on the other side of the
tunnel path and they are getting pruned. Not really a multicast guru, but
that's my thoughts on it.

What if the lab specifically specifies to use Sparse mode on the tunnel?
Thank you,

Try using sparse-dense on the path through the tunnel, i.e., allow the
auto-rp announcements through. These are 224.0.1.39(auto-rp send) and
224.0.1.40(ma-send).

Is there anything special that needs to be done in order to get Auto-RP to
work across a tunnel?
R6------------R2
R6
interface tunnel 0
ip address 140.10.200.6 255.255.255.0
tunnel source int s3/0.2
tunnel destination 140.10.102.2
tunnel mode dvmrp
ip pim sparse-mode
!
ip pim send-rp-announce BVI70 scope 5
ip pim send-rp-discovery scope 5
R2
interface tunnel 0
ip addres 140.10.200.2 255.255.255.0
tunnel source int s0/0
tunnel destination 140.10.102.6
tunnel mode dvmrp
ip pim sparse-mode
I see the auto-rp mapping on other routers, just not on R2.
Thank you,
Robert
