RFC4861 Neighbor Discovery – Sections 4.2 and 6.3.4

From section 4.2. Router Advertisement Message Format:

Cur Hop Limit        8-bit unsigned integer.  The default value that
                     should be placed in the Hop Count field of the IP
                     header for outgoing IP packets.  A value of zero
                     means unspecified (by this router).
