Hi All,
A new draft about EVPN DF election improvement is proposed. Handshaking mechanism is introduced to reduce traffic disruption in DF election or re-election scenario. 
Any comments and suggestions are appreciated.
Thanks,
weiguo

Abstract:
   In [EVPN], DF election process on each PE connecting to same ESI is
   triggered by independent timer expiring, DF and non-DF PEs can't
   ensure that unblocking and blocking action take effect at the same
   time, sometimes long time traffic disruption will occur. Handshaking
   mechanism for DF election is introduced in this draft, it can
   effectively reduce traffic disruption and avoid potential issues of
   packet duplication and loop in all-active access scenario.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
