Comment (by xavier@…):

 Replying to [comment:4 cyrus]:
 > Either remove the "option ipv6 1" stanca or use "option ipv6 auto" then
 the entire wan6 section is redundant. This is the new "magic" in CC.
 >
 > If you keep option ipv6 at any other value (e.g. 1 as in your example)
 you need to manually provide the the dhcpv6-section with ifname @wan.
 >
 > So summarizing for CC:
 >
 > option ipv6 empty / unset => IPv6 will be provided and the proto=dhcpv6
 section is not needed since its automatically created internally.
 >
 > option ipv6 auto => see above
 >
 > option ipv6 0 => disable IPv6 entirely for this PPP connection
 >
 > option ipv6 1 => only provide link-layer IPv6 (as in BB), you need to
 manually add the proto=dhcpv6 section in order to have IPv6 on layer 3.

 hi cyrus,

 there seems to be a disconnect between what you stated above, and what was
 written in the uci docs [1]:

 {{{
 ipv6    boolean         no      0       Enable IPv6 on the PPP link
 }}}

 is the default `0` or `auto`, in the absence of `option ipv6`? if `auto`
 then the docs should be updated to reflect this.
