   Edge RBridges currently learn the mapping between MAC addresses and
   their egress RBridges by observing the data packets traversed
   through. When ingress RBridge receives a data frame with its
   destination address (MAC&VLAN) unknown, the data frame is flooded
   across the TRILL campus. When there are more than one RBridge ports
   connected to one bridged LAN, only one of them can be designated as
   AF port for forwarding/receiving traffic for each LAN, the rest have
   to be blocked for that LAN.

   This draft describes the framework for using directory service to
   assist edge RBridges to improve TRILL network scalability in data
   center environment.
