Wow, how does pim sparse-mode over loopback0 on R2 make it work? I didn't
even see that Aky had a loopback interface configured or referenced anywhere
in his config's.
I've labbed several multicast scenarios similar to the one he did, but
without even using loopback interfaces on the spokes and it worked just
fine. At least I could ping several multicast groups that I created from
all routers.
I read through the page that Ramy referenced and didn't see anything that
stated that loopbacks are required when using multicast over frame or having
to create one on one of your spokes and apply pim to it even though it isn't
referenced in the configuration anywhere.
If anyone is seeing the connection, please share it with us.
Thanks,
Jason
