Look at CableLabs specifications. There is also RFC 7084, Basic
Requirements for IPv6 Customer Edge Routers which CableLabs

One of a stupidity, among many, of IPv6 is that it assumes
links have millions or billions of mostly immobile hosts
and define very large (but not large enough for billions or
even millions) minimum interval between ND messages, which
is applicable to links with much smaller number of hosts.
So, though rfc7084 says;
it MUST explicitly
invalidate itself as an IPv6 default router on each of its
advertising interfaces by immediately transmitting one or more
Router Advertisement messages with the "Router Lifetime" field
set to zero [RFC4861].
rfc4861 forbids two RAs sent with minimum interval less than 16
seconds.
Is it "immediately transmitting one or more Router Advertisement
messages"?
