All things related to multicast

[David Meyer <>]

        Here's what I propose.

        (i).    Let's use 239.0.0.0/8 for I2 scoped (non-global)
                groups 

        (ii).   Someone run a registry for the assignment
                of this space (I think that depending on
                sdr is too hard here, although such groups
                could be annouced this way). 

                Alternatively, we could use glop style address 
                assignment to get started. I'm in favor of this since
                everyone would know what they have, and there would
                be no administrative overhead. You would also know
                immediately which AS was sourcing the
                group. References for glop style:

        (iii).  Gigapops/customers leak 239/8 though both admin scope
                boundaries and SA filters with I2 networks. I2
                backbones must also forward (leak) packets and SAs
                from 239/8.
