Technical Summary

This draft describes how data network can benefit 
from non-Rbridge nodes peforming TRILL encapsulation with 
assistance from a directory servicve. 

RFC7067 and RFC8171 describe the framework nand methods for 
for TRILL edge Rbridges to get MAC&VLAN <---> Edge RBridge mappings 
from a directory service instead of flooding unknown destination MAC addresses
across a TRILL domain.  If it has the needed directory information, 
any node even an non-RBRidge node, can perform TRILL data packet encapsulation. 
This specification describes the benefits of and a scheme for 
non-RBridge nodes performing TRILL encapsulation. 

Working Group Summary

A complete directory service solution for TRILL was one of the 
key additions to the base specification needed by the industry. 
The TRILL working group designed the whole solution and its component
in discussions over 3-4  years.   This last group of specifications
depended on the approval of earlier specifications. 

Document Quality

Huawei plans an implementation of the protocol.
