Abstract:

   The Designated Forwarder (DF) in Ethernet Virtual Private Networks
   (EVPN) is defined as the Provider Edge (PE) router responsible for
   sending Broadcast, Unknown unicast and Multicast 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, Network Operators
   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.  This
   document updates RFC8584 by modifying the definition of the DF
   Election Extended Community.
