It seems that the following text on page 10 has some slight oversights: "
In order to respect the IPv6 Hop Limit value of the original datagram, a RPL router generating an SRH MUST set the Segments Left to no greater than the original datagram's IPv6 Hop Limit value upon forwarding. " should have been as follows: " In order to respect the IPv6 Hop Limit value of the original datagram, a RPL router generating an SRH in an IPv6-in-IPv6 tunnel MUST set the Segments Left to less than the original datagram's IPv6 Hop Limit value upon forwarding. " If the Segments Left is equal to Hop Limit value, the source route includes one more hop than the hop limit, which is not intended here. The other change is to make clear that the above phrase does not apply to the case where the SRH is directly included within the original packet. As a side note, the traceroute application doesn't seem to be able to handle the case with no tunnel use, because the original datagram destination address alters when SRH is added, unless, I guess, traceroute application is re-written to handle source routing in returned ICMPv6 error messages. Perhaps, that recommended direct inclusion of SRH should be removed? Best Regards, Kundok
