Nope. It is an extremally complex bunch of protocols on the1st  hope (between the computer and the router).

it's pretty simple really. Neighbor discovery is defined in RFC4861.

There's also formal updates in RFCs 8319, 8425, 9131, 5942, 6980, 7048, 7527, 7559, 8028, 9685, and 9762. Various other 
notes areincluded in 7217, 8978, 8981, and 4941.

After that rfc8415 defines DHCPv6, with extensions and various updates in 8156, 8168, 8639, 8948, 8987, 9527, 9663, 
9686 and 9818.

Obviously everyone needs yang so dhcpv6/yang is in 9243.

Then there's secure neighbour discovery. And ND proxy and LPWAN. Lots of RFCs there. 4943, 5269, 5909, 6273, 6494, 
6495, 6496, 6583, 6775, 6980, 7219, 7342, 8161, 8302, 8425, 8505, 8928, and 9131 for starters.

And plenty of other references inside other RFCs.

Oh yeah, and 15 errata for rfc4861 (there was another one confirmed earlier today and placed in HDU status):

https://urldefense.com/v3/__https://www.rfc-editor.org/errata_search.php?rfc=4861__;!!PtGJab4!57DPRrNyruxA8Q2B1ahrteRViMK7dG3RZN337PfO6jo87YpacGgKcycncaMqZGFlwpPY2ir02pLWUGD5HsZR_RhhfBw$
 [rfc-editor[.]org]

Hopefully this clearly shows to the OP that IPv6 neighbor discovery isn't remotely complicated.
