Description Michael Osipov 2020-11-07 15:19:44 UTC 
When you configure IPv6 for the first time having little knowledge about, no IPv6 address will resolve with the depicted configuration. Found in this ancient [1]
documentation is that 'no_radr' is the default. From a user's POV it is hard to understand from ifconfig manpage that this has to be set to "-no_radr" to have the default router added to the list.

Please update documentation to contain "inet6 -no_radr accept_rtadv". Mark the subsequent paragraph as for envs w/o local routers, but with static config.

Relevant in rc.conf: ipv6_cpe_wanif and ifconfig_⟨interface⟩_ipv6

Unsure about the interaction between -no_radr and accept_rtadv.
Comment 3 Sergio Carlavilla Delgado freebsd_committer freebsd_triage 2023-07-14 12:25:27 UTC 
The handbook working group created a new network chapter with basics about how to configure and IPv6 network.
I'm gonna close this PR. If in the future there are more problems/doubts with IPv6 we can open another PR and work with the last version of the Handbook.
