TEST PROCEDURE

- Verify that a host properly discards an invalid Router Advertisement.

1. Send RA

        IPv6 header
            hop limit          = 2
            source             = TR1 (link-local)
            destination        = all-nodes multicast address
        RA
            cur hop limit      = 64
            M                  = 0
            O                  = 0
            router lifetime    = 20
            reachable time     = 600000
            retrans timer      = 1000
        SLL option
        Prefix Information option
            prefix length      = 64
            L                  = 1
            A                  = 1
            valid Lifetime     = 2592000
            preferred lifetime = 604800
            prefix             = 3ffe:501:ffff:100::

3. Send Echo Request

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

4. Observe MAX_MULTICAST_SOLICIT NSs

        IPv6 header
            hop limit   = 255
            source      = HUT (link-local)
            destination = TR1 (solicited-node multicast address)
        NS
            target      = TR1 (link-local)
        SLL option

        Node constants:
            MAX_MULTICAST_SOLICIT: 3 transmissions
