Need to be follow up on mailing list. 4. draft-skr-bess-evpn-redundant-mcast-source-00      Jorge Rabadan           10 min Ali: is DF election for particular (S,G). since per flow DF election exist, can we leverage per flow DF election. Since DF election is for ingress traffic. Current DF election is limited to per ES, and per flow would provide more granularity. Stig : does it work only for SM or works for SSM too Jeffery: it would work for SSM and SM both. Stig: it did require certain deployment to have group address. Can we signal per (S,G) Jeffery: it was thought about, it would be hard to implement. Source prefix would be good option. 5. draft-sajassi-bess-evpn-ac-aware-bundling-00       Mankamana Mishra        10 min Steven: how is it different from Vlan aware service Ali: it would avoid having multiple IRB interface . some platform might not be able to support high number of bride domain, this solution provides solution to those platforms.
