MPR_e2_dst_unr.seq - check Message Processing Rules (ICMPv6
Destination Unreachable )
Host and Router
MPR_e2_dst_unr.seq [-tooloption ...] -p MPR_e2_dst_unr.def
When test stars, states of Neighbor Cache Entry for TN's
addresses are reachable.
This test verifies that the message processing rule ,
(e) An ICMPv6 error message MUST NOT be sent as a result of
receiving:
(e.2) a packet destined to an IPv6 multicast address (there are
two exceptions to this rule: (1) the Packet Too Big
Message - Section 3.2 - to allow Path MTU discovery to
work for IPv6 multicast, and (2) the Parameter Problem
Message, Code 2 - Section 3.4 - reporting an unrecognized
IPv6 option that has the Option Type highest-order two
bits set to 10), or
TN NUT
---------------------------
1.
=== UDP packet ===>
src address : TN link local address
dst address : all node multicast address
port number is not used in NUT
2.
<< JUDGMENT >>
<=== No pakcet ===
or
<=== ICMPv6 Destination Unreachable ===
Code is 4
<< PASS >>
NUT do not send ICMPv6 Destination Unreachable.
<< FAIL >>
NUT send ICMPv6 Destination Unreachable.
