I have a singlewire informacast setup working with PIM Sparse Dense mode across multaple sites. I have one meraki enviroment that I need to set up multicast routing to as well.
currently all my interfaces are configured with "ip pim sparse-dense-mode" and nothing else. My meraki equipment only suppors PIM-SM. I know for SM I need to set a RP and am wondering if I set a RP will that break my other sites on Sparse-Dense mode and what is the best way to set that up.
topology working down from source to destination.
