NimbostratusCannot automatically add the LTM virtual server to DNS
Hi Team,
I'm having an issue while configuring GTM. DNS is able to connect to the BIG-IP LTM, but it cannot automatically add the LTM virtual servers to DNS. I checked the iqdump, and it does contain information related to the LTM virtual servers, but I still don't see any VS entries in the GUI.
iqdumpThe BIG-IP DNS server is showing 0 virtual serversLTM VS is Available
After that, I tried to manually add the LTM virtual servers, but it showed this error message: 'no reply from big3d: timed out'.

Hi,
Checking the iqdump shows that TCP port 4353 is allowed between the BIG-IP DNS system and the target BIG-IP systems. There is no router or firewall between the DNS and the LTM, so there is no network address translation involved. I have already enabled these features, but I still don't see any VS entries in the GUI.

Have you created a LTM entry in GTM here
DNS → GSLB → ServersCheck the virtual server
tmsh show gtm server <server-name> virtual-servers
