INITIALIZATION

TEST PROCEDURE

- Verify that NUT updates entry's reachablity state to INCOMPLETE
- Verify that NUT transmits valid NS in INCOMPLETE state

   TN1     NUT
    |       |
    | ----> | NS (unicast)
    | ----> | Echo Request
    |   <-- | NS (multicast) [Judgment #1]
    |   <-- | NS (multicast)
    |   <-- | NS (multicast)
    |       |
    V       V

    State: NONE (TN1) (link-local)

1. Send NS

        IPv6 header
            hop limit   = 255
            source      = TN1 (link-local)
            destination = NUT (solicited-node multicast address)
        NS
            target      = NUT (link-local)
        SLL option

    State: INCOMPLETE (TN1) (link-local)

2. Send Echo Request

        IPv6 header
            source      = TR1 (link-local)
            destination = HUT (link-local)
        Echo Request

3. Observe MAX_MULTICAST_SOLICIT NSs [Judgment #1]

        IPv6 header
            hop limit   = 255
            source      = NUT (link-local)
            destination = TN1 (link-local)
        NS
            target      = TN1 (link-local)
        SLL option

        Node constants:
            MAX_MULTICAST_SOLICIT: 3 transmissions

    State: NONE (TN1) (link-local)

JUDGEMENT

[Judgment #1] NUT must transmit NS to TN1

CLEANUP

none
