FabricPath & PIM-SM Interoperation (OT)

Hello everyone,

I posted this on c-nsp, and really didn't get the kind of answers I was
looking for. Hopefully there is someone out there that can dive a little
deeper into this topic.

Basically, I would like to know the details on how a switch running FP
(Nexus 7k or 5k) deals with multicast sources/listeners that are inside a
FP domain, when it is running PIM-SM on a L3 interface(SVI) that is
connected to some other part of the network ( that isn't running FP).

For example, my understanding is that a FabricPath edge switch will flood
GM-LSPs if it has an interested listener for a multicast group. When the FP
switch that is also running PIM-SM on its L3 interface sees this, it would
make sense for it to send a PIM-Join message to its neighbor, toward the
RP. The same thing should happen with multicast sources, and PIM Register
messages.

Does anyone have experience with this? Is my assumption correct here? Any
details would be appreciated, as the Cisco documentation on this topic is
quite limited.

Thanks,

YuriB.
