NAME

        Err_Condition_Port_Unreachable.seq - UDP Port Unreachable (Routers and Hosts)

TARGET

        Host/Router

SYNOPSIS

        Err_Condition_Port_Unreachable.seq [-tooloption ...] -p Err_Condition_Port_*.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 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.

        TN                      NUT

                src address : does not identify a single node uniquely 
                dst address : NUT global address
                         port number is not used in NUT (9000)

JUDGEMENT

    << PASS >>
    The NUT must not send a Destination Unreachable Error Message to TN 
    when it receives a UDP packet for an unreachable port.
