An alternative to the default Designated Forwarder (DF) selection
algorithm in Ethernet VPNs (EVPNs) is defined.  The DF is the
Provider Edge (PE) router responsible for sending Broadcast, Unknown
Unicast, and Multicast (BUM) traffic to a multihomed Customer Edge
(CE) device on a given VLAN on a particular Ethernet Segment (ES).
In addition, the ability 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 services.  Therefore, it updates the EVPN
specification (RFC 7432).

This document is a product of the BGP Enabled Services Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
