> The router is set with ... a global unicast IPv6 address (GUA) prefix 2001:db8:abc:123::/64, which the ISP designates to us (of course, that’s not the real prefix, but I will use this one in all examples below). On a side note, I have more trust in documentation that is compliant with the relevant RFCs (i.e., RFC1918, RFC3849, RFC5737, et al). In my experience, such documentation is much more likely to be "technically correct" and get the small details right.
