[knot-resolver-users] forward policy stub kind of round robin

Hello, I have at the moment a network with 3 DNS servers. They do recursive/caching as well as authorative zones (Bind 9). I want to build a structure with 2 authorative Servers using Knot-DNS and 3 resolvers using Knot-Resolver. As our authorative servers are in our network and as I want to get any changes in their zones as fast as possible to our users I use from the documentation: Replacing part of the DNS tree Interesting is this line: policy.add(policy.suffix(policy.STUB({'$our ip'}), extraTrees)) Can I put more than one IP at this line to forward the queries? We have 2 authorative servers, so I want ask both of them round robin like. In my config I have comma separated two servers, kresd is running with it, but it seems it uses only the first. Is there a way to get my desired behavior? Regards Thomas P.S.: Versions are Knot-Resolver 3.2.1 and OS is Ubuntu 18.04.02 -- Thomas Belián Fachhochschule Erfurt Fak.
