Abstract:
   The Designated Forwarder (DF) in Ethernet Virtual Private Networks
   (EVPN) is defined as the PE responsible for sending Broadcast,
   Unknown unicast and Broadcast traffic (BUM) to a multi-homed device/
   network in the case of an all-active multi-homing Ethernet Segment
   (ES), or BUM and unicast in the case of single-active multi-homing.
   The Designated Forwarder is selected out of a candidate list of PEs
   that advertise the same Ethernet Segment Identifier (ESI) to the EVPN
   network, according to the Default Designated Forwarder Election
   algorithm.  While the Default Algorithm provides an efficient and
   automated way of selecting the Designated Forwarder across different
   Ethernet Tags in the Ethernet Segment, there are some use cases where
   a more 'deterministic' and user-controlled method is required.  At
   the same time, Service Providers require an easy way to force an on-
   demand Designated Forwarder switchover in order to carry out some
   maintenance tasks on the existing Designated Forwarder or control
   whether a new active PE can preempt the existing Designated Forwarder
   PE.

   This document proposes a Designated Forwarder Election algorithm that
   meets the requirements of determinism and operation control.
