# Test Purpose and Description:
|
|
# -----------------------------
|
|
# The purpose of this test case is to validate that the DUT is able to generate
|
|
# Address Notification messages in response to Address Query messages.
|
|
#
|
|
# - Build a topology that has a total of 16 active routers, including the Leader,
|
|
# with no communication constraints and
|
|
# - MED only allows Leader
|
|
# - DUT only allows Router1
|
|
# - DUT allows BR later as required in step 5.
|
|
# - The Leader is configured as a DHCPv6 server for prefix 2001::
|
|
# - The Border Router is configured as a SLAAC server for prefix 2002::
|
|
#
|
|
# Test Topology:

# MED

# Router_15 - Leader
