# py-libdnet          python interface to libdnet
# scapy               powerful interactive packet manipulation in python

# This test needs a manual setup of two machines
# Set up machines: SRC DST
# SRC is the machine where this makefile is running.
# DST is running OpenBSD with pf to test the neighbor discovery states.

# RFC 4861 7. describes the following test cases for ND:
#
# Duplicate Address Detection
# - request  NS from unspecified address to target solicitated-node multicast
# - response NA from interface address   to all-nodes multicast
#
# Address Resolution
# - request  NS from interface address   to target solicitated-node multicast
# - response NA from interface address   to source of NS
#
# Unsolicited Neighbor Advertisements
# - request  NA from interface address   to all-nodes multicast
#
# Neighbor Unreachability Detection
# - request  NS from interface address   to target unicast
# - response NA from interface address   to source of NS
