   This document describes mechanisms to optimize the ARP (Address
   Resolution Protocol) and ND (Neighbor Discovery) traffic in a TRILL
   campus. TRILL switches maintain a cache of IP/MAC address/Data Label
   bindings that are learned from ARP/ND requests and responses that
   pass through them. In many cases, this cache allows an edge RBridge
   to avoid flooding an ARP/ND request by either responding to it
   directly or by encapsulating it and unicasting it. Such optimization
   reduces packet flooding over a TRILL campus.
