# Test Purpose and Description:
# -----------------------------
# The purpose of this test case is to validate that DUT will
# attach to a REED with the highest link quality, when routers
# with the highest link quality are not available.

# Test Topology:
# -------------
# Leader
# / \
# Router2 REED1
# \ /(better link_quality)

# ----------
