1. Reboot

2. Observe RS

        RS message format #1
            IPv6 header
                hop limit   = 255
                source      = unspecified address
                destination = all-routers multicast address
            RS

        RS message format #2
            IPv6 header
                hop limit   = 255
                source      = HUT (link-local)
                destination = all-routers multicast address
            RS
            SLL option

        RS message format #3
            IPv6 header
                hop limit   = 255
                source      = HUT (link-local)
                destination = all-routers multicast address
            RS

JUDGEMENT

[Judgment #1] The HUT should transmit up to MAX_RTR_SOLICITATIONS (3) Router Solicitations RTR_SOLICITATION_INTERVAL (4) seconds apart.
The Router Solicitations should be sent from either the link-local address of the HUT or the unspecified address.
The destination address should be the All-Routers multicast address.
The Router Solicitations may or may not include a Source Link-layer Address option.
