I am network admin, but what router advertise is out my easy control 
(fixing configs in the Linux router's FS or even rebuilding router 
components is needed, I don't want to touch this hardware).

I want override because router runs dnsmasq with caching (on both its IPv4 
and IPv6 adresses), and NS it advertise goes through tunnel each time 
without caching in the router.

So far I found the way to specify router link-local address using
name_servers=fe80::...
in the /etc/resolvconf.conf
It prepends this name server above all others router advertise. But I 
still not find the way to _exclude_ what router advertise, 
perhaps looking into rtsol(8) possibilities you point will help here.
