RFC7706 and Unbound

[Eduardo Schoedler]

Hi people,

According to the RFC 7706 [1], I can configure my Unbound to query to
my local NSD about root-servers.

When I add this in my config file, unbound ignores it:

# Configuration for Unbound
   server:
       do-not-query-localhost: no
   stub-zone:
       name: "."
       stub-prime: no
       stub-addr: 127.12.12.12

# unbound-checkconf
[1463430134] unbound-checkconf[64497:0] error: second hints for zone . ignored.
unbound-checkconf: no errors in /etc/unbound/unbound.conf

Why is this?

Thank you.
