Benchmarking the Neighbor Discovery Protocol
Abstract
This document provides benchmarking procedures for the Neighbor
Discovery Protocol (NDP). It also proposes metrics by which an NDP
implementation's scaling capabilities can be measured.
Status of This Memo
This document is not an Internet Standards Track specification; it is

1. Introduction
When an IPv6 node forwards a packet, it executes the following
procedure:
o Identifies the outbound interface and IPv6 next hop.
o Queries a local Neighbor Cache (NC) to determine the IPv6 next
hop's link-layer address.
o Encapsulates the packet in a link-layer header. The link-layer
header includes the IPv6 next hop's link-layer address.
o Forwards the packet to the IPv6 next hop.
