Med: It was there; see http://tools.ietf.org/html/draft-ietf-softwire-dslite-multicast-00#appendix-A.1. I failed to find back why we removed it in -01 of the draft. BTW, this is not a diffrent use case, only the way data is handled differs. > >The 6-4-6-4 use case is also high priority, requires IGMP/MLD >translation, and is not covered by the softwire draft. Med: I'm not sure there is a consenus about the urgency of 6-4-6-4 scenario. I knwo there is an operator representative voicing for it, but I always failed to understand that use case. > >So we're looking at at least three use cases of IGMP/MLD translation, >possibly more, of which only one is covered by the softwire draft.

What is wrong with LCing this in PIM and MBONED? _______________________________________________ Softwires mailing list [email protected] https://www.ietf.org/mailman/listinfo/softwires
