Hi Susan & Jeffrey,

Now multicast is an important service in the network such as IPTV, etc. But there are complex choice for multicast solutions including L2 multicast vs. L3 multicast, public multicast vs. multicast VPN, multicast based on PIM/BGP/mLDP/P2MP TE/IGP/Ingress replication which make the multicast provision difficult. This may be simplified through the I2RS intefaces. Could we define the multicast usecase in I2RS WG? And how will we define the multicast usecase: enhancing the draft-ietf-i2rs-usecase-reqs-summary-00 to incorporate multicast use cases or proposing independent multicast use case draft?

Best Regards,
