problem with topology (bigip dns version 12.x.x)
Hello, I'm considering upgrading to version 12.x.x. but I found that topology doesn't work under specific condition.
All types of resources are "CNAME".
condition: 1. Wide IP (A) :
2. pool1(cname) : 1.com
pool2(cname) : 2.com
3) DNS Express or named : CNAME 3.com.
4)loadbalancing mode : topology
region1 : poo1 weight 100
region2 : poo2 weight 50
test: in region2, when I look up domain " A".
bigip dns(gtmd) responses "2.com". It works well.
but when I lookup DNAME,TXT,etc, Bigip dns(named or dnsexpress) responses "3.com".
it's wrong. and recursive dns can be cached. it's problem.
(When I set wideip(CNAME) under same condition, I got same results )
When CNAME resource, it depends on CNAME resource regardless of type.
in case, gtmd have to response, not named(or zxfrd).
to solve problem, what can I register data with named or zxfrd? help me, please.
