    Well, once a draft is posted, it can't be changed, so the currently
    posted -01 won't change but the -02 version that is being worked on
    and is not yet posted eliminates the alternative encapsulation.

[JORGE] :-) of course. I misunderstood your answer. Sounds good then. Thank you!
    
    Thanks,
    Donald

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.
