# Test Purpose and Description:
# -----------------------------
# The purpose of this test case is to validate the minimum
# conformance requirements for router-capable devices:
# a)Minimum number of supported children.
# b)Minimum MTU requirement when sending/forwarding an
# IPv6 datagram to a SED.
# c)Minimum number of sent/forwarded IPv6 datagrams to
# SED children.
