Hello
I have this kind of forwarders configuration. 192.168.100.1 has 3ms RTT
192.168.200.1 has 150ms RTT
options {
forwarders {
192.168.100.1;
192.168.200.1;
};
};
Usually all queries go to 192.168.100.1 but occasionally it experiences
high load which obviously has effect on SRTT.
This causes that 12% of the queries are forwarded to 192.168.200.1.
I want that 192.168.200.1 is used only when 192.168.100.1 is down or is
experiencing really high latency.
I tried adding 192.168.100.1 multiple times in forwarders section but
it didn't help.
Is there any way around this?
Any way to manually tweak SRTT per server?
