Edge TRILL (Transparent Interconnection of Lots of Links) switches
currently learn the mapping between MAC (Media Access Control)
addresses and their egress TRILL switch by observing the data packets
they ingress or egress or by the TRILL ESADI (End-Station Address
Distribution Information) protocol. When an ingress TRILL switch
receives a data frame for a destination address (MAC&Label) that the
switch does not know, the data frame is flooded within the frame's
Data Label across the TRILL campus.
This document describes the framework for using directory services to
assist edge TRILL switches in reducing multi-destination frames,
particularly unknown unicast frames flooding, and ARP/ND (Address
Resolution Protocol / Neighbor Discovery), thus improving TRILL
network scalability and security.
This document is a product of the Transparent Interconnection of Lots of Links Working Group of the IETF.
