I'm positive you're already familiar with all this, but just for the archives: Inclusive trees eliminate the need for too much state in the core, but requires that all Receiver PE routers are aware about the Multicast infrastructure regardless of whether they have downstream listeners or not. Selective trees are the exact opposite. You can choose which Receiver PE routers will handle Multicast information so only interested receivers attract traffic to the right Receiver PE routers, but it increases the amount of state in the core. I would really like to see how mLDP plays into this whole mix. Cheers, Mark.
