3.  draft-salam-bess-evpn-oam-req-frmwk-01             Donald Eastlake         10 min

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.

    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. But customers are 
        ready to make sure MAC are unique across different subnet.
    Sami: how would BUM traffic be forwarded.
    Ali: This solution is going to work for IRB solution.

6.  draft-sajassi-bess-secure-evpn-00                  Ali sajassi             10 min

    Ali: Term PE is used as C-PE . if needed, clarification can be added.
    Steven: is this same as Erics draft ?
    Ali: this draft is solving completing different problem statement. There is no overlap.
    Steven: We do not want to have multiple solution for same problem statement.
    Keyur: There is separate work going on in L3VPN. We should see if it can be made generic.
