Thanks for the pointer and the research!

Did a quick read of the article. So.. it would seem the vast majority of
OSes don't implement RFC6980, yet? -- Sad..

I'm curious about the structure of the packets for "two frags, two dest
options in fragmentable part" and "four frags, two dest opts in
fragmentable part". i.e., size of options, and size of headers -- trying
to figure out why the former didn't circumvent RA-Guard, but the later did.

I guess that, in-line with the aforementioned sadness, there's also
sadness that there's not much RFC7113 in Cisco's RA-Guard land...
