CNAME and A record in F5 DNS

Hello have you followed this?:

Pay attention to this:

*********

If you want the BIG-IPDNS to respond to both A and CNAME record type requests, you must configure two wide IPs. One wide IP of type A with a CNAME pool type, and a second wide IP of type CNAME with a CNAME pool type. At a minimum, an A record type wide IP should be configured with a CNAME pool.

If the CNAME that dns is being redirected is not another Wide IP on the F5 device with a normal A record pool that can give real DNS resolution to the client LDNS then read:

Note: If you want BIG-IP DNS to use a CNAME record that does not exist on the device, check the Static Target box and type in CNAME (such as test.com) for Wide IP .
