   An alternative to the Default Designated Forwarder (DF) selection
   algorithm in Ethernet VPN (EVPN) networks is defined. The DF is the
   Provider Edge (PE) router responsible for sending broadcast, unknown
   unicast and multicast (BUM) traffic to multi-homed Customer Equipment
   (CE) on a particular Ethernet Segment (ES) within a VLAN. In
   addition, the capability to influence the DF election result for a
   VLAN based on the state of the associated Attachment Circuit (AC) is
   specified. This document clarifies the DF Election Finite State
   Machine in EVPN, therefore it updates the EVPN specification.
