This document describes mechanisms to optimize the Address Resolution
Protocol (ARP) and Neighbor Discovery (ND) traffic in a Transparent
Interconnection of Lots of Links (TRILL) campus.  TRILL switches
maintain a cache of IP / Media Access Control (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
Routing Bridge (RBridge) to avoid flooding an ARP/ND request by
either responding to it directly or encapsulating it and unicasting
it.  Such optimization reduces packet flooding over a TRILL campus.

This document is a product of the Transparent Interconnection of Lots of Links Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
