When test starts, states of Neighbor Cache Entry for TN's addresses are reachable. =head1 TEST PROCEDURE This test verifies that the message processing rule, An ICMPv6 error message MUST NOT be sent as a result of receiving: 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). TN NUT --------------------------- 1. === fragmented (1st) packet ===> src address : TN link local address dst address : all node multi cast address 2. << JUDGEMENT >> <=== No packet === or <=== ICMPv6 Time Exceeded === Code is 1 =head1 JUDGEMENT << PASS >> NUT do not send ICMPv6 Time Exceeded. << FAIL >> NUT send ICMPv6 Time Exceeded. =head1 REFERENCE RFC2463 2.4 Message Processing Rules Implementations MUST observe the following rules when processing ICMPv6 messages (from [RFC-1122]): =begin html 

    (e) An ICMPv6 error message MUST NOT be sent as a result of
        receiving:

         (e.1) an ICMPv6 error message, or

         (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

         (e.3) a packet sent as a link-layer multicast, (the exception
               from e.2 applies to this case too), or

         (e.4) a packet sent as a link-layer broadcast, (the exception
               from e.2 applies to this case too), or

         (e.5) a packet whose source address does not uniquely identify
               a single node -- e.g., the IPv6 Unspecified Address, an
               IPv6 multicast address, or an address known by the ICMP
               message sender to be an IPv6 anycast address.
