Observable Results

  Step 2: The RUT must transmit valid Router Advertisements that satisfy all of
          the following validity checks:
    - IP Source Address is a link-local address.
    - The IP Hop Limit field has a value of 255, i.e., the packet could not possibly have been
       forwarded by a router.
    - If the message includes an IP Authentication Header, the message authenticates correctly.
    - ICMP Checksum is valid.
    - ICMP Code is 0.
    - ICMP length (derived from the IP length) is 16 or more octets.
    - All included options have a length that is greater than zero.
