Your configuration works based on the RTT (Round Trip Timer) i.e the server
that responds the quickest based on initial checking
Algorithm....

Subject: Issue with Forwarding(URGENT!!!)
Hi ,
I have some problem in forwarding feature of bind 9.2 based DNS server.
The configuration done in my DNS server , which is BIND 9.2 is
mentioned below
options{
recursion true;
allow-recursion {any;};
forward first;
forwarders {x.x.x.x; y.y.y.y;};
}
Details of server version in the forwarder list:
x.x.x.x is Solaris (Bind 8.2) and y.y.y.y is( BIND 9.2) server.
The problem is in query forwarding for some off site records . When
ever you try to query any record which is not present in the
authoritative data of my DNS server , it forwards to the DNS server in
the forwarder list mentioned above. Now my problem is , whenever my 1st
server(i.e. BIND 8.2) not able to respond the query for whatever reason
, queries are not getting forwarded to the other server in the list .But
if I reverse list in forwarder option is works fine for me. Is there any
compatibility issue here???
I just want to know how exactly it works in BIND 9.2 ? It works in
round robin manner or from left to right ??
Can any body suggest me , where is the problem ??? I am interested to
know the implementation logic of forwarding in BIND 9.2. source code.
Since it's very urgent , I will appreciate your early response.
Thanks in advance,
Sanjib
