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.
* None.
