Hi Donald,

Thank you for this.
For the second question, I get from your answer that you will keep both encapsulations for the time being? 

Thanks.
Jorge

    Thanks for sending comments.
    
    > - In the last IETF, I suggested the use of BGP and the BGP-BFD attribute to exchange discriminators, as in section 3.1.6 of draft-ietf-bess-mvpn-fast-failover. The idea seemed to be accepted, but it is not in the new version. This would allow the signaling of the discriminators along with MAC/IP routes, IMET routes, AD per-EVI routes, IP-Prefix routes, etc. without the burden of having to support the EVPN LSP-ping draft.
    
    There is a draft version -02 in the works intended to include
    distribution of BFD discriminators in BGP but this revision was not
    completed to the agreement of the authors in time to posted before
    this meeting.
    
    > - The draft describes an encapsulation and an alternative encapsulation. Is the intend to keep both? Wouldn't be better to leave only one to ease implementations and interoperability?
    
    Currently, the candidate version -02 draft dispenses with with the
    alternative encapsulation.
    
    Thanks,
    Donald
