Thanks Josh,
Topology is 4 routers all in a full-mesh and all using main interface
(multipoint default). So, whichever router the multicast source comes
through going to another site, the issue arises in my opinion. Answer is I
put on all 3 routers participating in the multicast network.
Catch is solution puts on only Router-RP and later task says source is
behind the RP. Still If I had a question just asking for PIM-SM to be set up
on such a topology, does not specify source explicitly what would the advice
be? Or would this only be valid on RP? Though one would expect RP was chosen
with multicast source taken into consideration. Though I would risk the lab
on such assumptions.
Any thots?
Bola

Question,
In your lab did you put ndma mode on ALL the interfaces? I think that's your
dilemma. Is the topology a hub and spoke? I believe it may be....You only
need NBMA mode on the hub mate, If that's what you did then I think your
good to go. Think about what NBMA mode does and if the scenario called for
it I think you are ok. Commands in the real lab will most likely not be
explicity mentioned...your expected to know what goes where unless they tell
you yes or no.
regards,
josh
