Multicast Routing Clarification
New to the forums, not new to the products. I was curious if anyone can clarify a very vague statement. When referring to https://watchguard.com/help/docs/help-center/en-US/Content/en-US/Fireware/networksetup/multicast_about_c.html in the Help Center I find the following line "Your Firebox supports PIM Sparse Mode (PIM-SM) which is used when only a few devices subscribe to the multicast. These devices are multicast receivers. Receivers can be located anywhere in the world, on any network, and compose the multicast group logical group." I come from a world where "a few" relates to less than 5.
Does anyone have some real world experience that can expand upon this statement. I have a situation that requires multicast traffic. Between clients and gateways I'll need close to 30 or 40 receivers.
