[RFC7067] gives a problem statement and high-level design for using directory servers to assist TRILL [RFC6325] [RFC7780] edge nodes in reducing multi-destination ARP / Neighbor Discovery (ND) [ARPND], reducing unknown unicast flooding traffic, and improving security against address spoofing within a TRILL campus. Because multi-destination traffic becomes an increasing burden as a network scales up in number of nodes, reducing ARP/ND and unknown unicast flooding improves TRILL network scalability. This document describes specific mechanisms for TRILL directory servers.

Transparent Interconnection of Lots of Links (TRILL): Edge Directory Assistance Mechanisms
This document describes mechanisms for providing directory service to TRILL (Transparent Interconnection of Lots of Links) edge switches. The directory information provided can be used in reducing multi- destination traffic, particularly ARP / Neighbor Discovery (ND) and unknown unicast flooding. It can also be used to detect traffic with forged source addresses.
