Have a simple set with three routers
R2--------R5(RP)--------R3
Its running all sparse mode. R2 has an igmp join statement
for 225.25.25.25 and R3 is sending a ping to this group
source from 35.35.35.3. Below is the mroutes I see on R3
the source of the stream. I am experimenting with set the
spt threshold to infinity on R3 below is the different mroute
outputs:
Default setup no SPT threshold changed

My questions:
1. Why do I not see any outgoing interfaces in either output
for (35.35.35.3, 225.25.25.25),
2. In the default SPT setup how come I see the "Registering"
going on and on and on.....
Thanks & Regards
Kevin
