   Edge RBridges currently learn the mapping between MAC addresses
   and their egress RBridges by observing the data packets traversed
   or by the TRILL ESADI protocol. When ingress RBridge receives a
   data frame whose destination address (MAC&VLAN) that RBridge does
   not know, the data frame is flooded within the VLAN across the
   TRILL campus.

   This draft describes the framework for using directory services
   to assist edge RBridges by reducing multi-destination frames,
   particularly unknown unicast frames flooding, and ARP/ND,
   improving TRILL (Transparent Interconnection of Lots of Links)
   network scalability in environments such as data centers.
