# -----------------------------

# The purpose of this test case is to validate that the DUT is able to

# maintain an EID-to-RLOC Map Cache for a Sleepy End Device child attached to
|
||
# it. Each EID-to-RLOC Set MUST support at least four non-link-local unicast
|
||
# IPv6 addresses.
|
||
#
|
||
# Test Topology:
|
||
# -------------
|
||
# Router_1 - Leader

# | / \
|
||
# SED MED_1 .. MED_4
|
||
