What are the forwarding rules for forwarding servers in named.conf?
Description
named.conf as the following configuration.
forward only; forwarders { 6.27.56.109;6.27.56.110; };
The {6.27.56.109;} as the next-level dns service node has been shutdown, and 6.27.56.110 is active. When I make a forward domain name request, the following error occurs
; <<>> DiG 9.11.21-9.11.21-4.h9.eulerosv2r10 <<>> @127.0.0.1 lwj.233.com ; (2 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached
Request
I want to know the forwards rules in named.conf forwards config. It doesn't working in Round-Robin Scheduling? when one node been shutdown, and forward to the other node?
forwarders { 6.27.56.109;6.27.56.110; };
Is any health check algrithom working in foewarders list?
