bind 9 - lwresd - lwres_getrrsetbyname, load balancing doesn't work
Hi, I run a bind name sever as lwrsed and use lwres_getrrsetbyname to resolve a domain name, But for some reason I always get a the records in the same order (priority). When I bypass the lwres_getrrsetbyname and use nslookup to resolve a domain name, the daemon returns the records in the order I set by adding rrset-order option to the configuration file. Do you have a clue what could be the problem? Is it possible that the light weight resolver doesn’t support load balancing in lwres mode?
