Agree with all you're writing; IMHO, MBGP should not be a requirement. There is an operational problem though, but it's of wider scope then just SSM. That is, if you do use MBGP, e.g., have an MBGP default route, how do you handle those multicasters which don't advertise their address space with MBGP. In other words, there will inevitably be some amount of mess when you try to combine multiple protocols as information sources... -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
