The DNS documentation I am reading
( indicated
that "Secondary name servers provide redundancy and load balancing for a
domain." But I've read here where that really is not the case

Is the documentation misleading? Has anyone figured out how to load
balance two DNS servers? I also read somewhere in the documentation about
the ability to round-robin (can't find paragraph presently). Is that also
not accurate?

Finally, is there a clear step-by-step anywhere for configuring a
secondary DNS server? I've configured a second DNS server and associated
it with secondary zone, but it does not seem to be doing a zone transfer,
and cannot resolve names.

Thank you.
