NAME

        Err_Condition_Unknown_Option.seq - Echo Request with Unknown Option in Destination Options (Routers and Hosts)

TARGET

        Host/Router

SYNOPSIS

        Err_Condition_Unknown_Option.seq [-tooloption ...] -p Err_Condition_Unknown_Option_*.def

INITIALIZATION

        Common Test Setup 1.1

TEST PROCEDURE

Verify that a node properly handles the reception of an error condition caused by a packet with a source address that does not uniquely identify a single node.

        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.
         === IPv6 packet  ===>
                src address : does not identify a single node uniquely
                dst address : NUT global address
                        option:135(unknown,msb:10)

         <=== No pakcet ===

JUDGEMENT

    << PASS >>
    The NUT must not send a Parameter Problem Error Message
    when it receives an ICMPv6 Echo Request with an unknown option with highest bits 10.
