TRILL (Transparent Interconnection of Lots of Links) active-active
service provides end stations with flow-level load balance and
resilience against link failures at the edge of TRILL campuses, as
described in RFC 7379.

This document specifies a method by which member RBridges (also
referred to as Routing Bridges or TRILL switches) in an active-active
edge RBridge group use their own nicknames as ingress RBridge
nicknames to encapsulate frames from attached end systems.  Thus,
remote edge RBridges (who are not in the group) will see one host
Media Access Control (MAC) address being associated with the multiple
RBridges in the group.  Such remote edge RBridges are required to
maintain all those associations (i.e., MAC attachments) and to not
flip-flop among them (as would occur prior to the implementation of
this specification).  The design goals of this specification are
discussed herein.

This document is a product of the Transparent Interconnection of Lots of Links 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
