All, We have a set of BIND primary servers (MASTERs) and a set of secondary servers (slaves to the MASTERs). The secondary BIND DNS servers disabled recursion ( with "*recursion no;" *) in the global options. All the applications/systems do use secondary DNS servers for name resolution.
Now there is a need to configure a forwarding zone in the "secondary DNS servers" to an external DNS server. In this scenario, in-order for the secondary server to forward the DNS query to an external DNS server, is it required to enable the recursion in the global options on the secondary servers? Based on reference material, I did not see such a requirement. But my observation is the query is not getting forwarded ( tried to check using the packet trace) When recursion is enabled, the query is getting forwarded. The BIND version I am using is 9.11.2.x. Appreciate your ideas and help. Thank you Kind Regards, Ravi Kota
