Nice! I love it Spencer : )

I suggest a slight adaptation to show that with the current specs, the device is the endpoint for the tunnel and the destination of inner packet as well.

Hi, Pascal,

Thanks for the quick response. Inline.

Hello Spencer,

The 2 shorter arrows, left and right, represent the encapsulation tunnel.

Now that you've said that, I totally get it, but I didn't get that from the picture at all.

Would you have a suggestion to improve the readability?

Maybe :-)

I lengthened the native IPv6 arrow and used different endpoints for the tunnel, hyphenated "IPv6-in-IPv6, and included "tunneled using" in the label (I probably didn't use the right words, but you'd know what is correct).

In figure 2, I'm a bit confused on what the third-from-the-left vertical line represents - is it also IPv6 in IPv6 plus RPL SRH, or something else?
