I do not know of Comcast's Ethernet services specifically, but a general problem with carrier Ethernet services that are based upon the Metro Ethernet Forum (MEF) is that PIM-snooping is not implemented for multicast traffic. The absence of PIM-snooping results in the carrier's Ethernet service operating like a 1990's style Ethernet hub in which (S,G) multicast packets are incorrectly flooded out all user ports.
Not implemented because it's not in the MEF specs or not implemented because of carrier operational practice?
