DNS Resolver for System Configuration not working

Hi ,

 

Is there a way to check which name server LTM would consider using which it would create the ephemeral node ? I have 4 configured 2 are reachable and 2 are unreachable. Still LTM is not creating the ephemeral node. Any suggestions would be helpful.

  • Suggestions: If 2 ​ephemeral node is resolving out of 4 mean dns is resolving ip address.

    Did ​you run the dig command to check right name server?

    Try below command.​ Example:

    dig example.com +short +identify
    dig foo.example.com +all

    ​Let's us know the issue.

    Thanks​

      Hi Samir,

       

      I meant i have 4 name servers configured. But ephimeral node still doesn't populate.

       

      Out of 4 two name servers are reachable from device and 2 are not reachable. Ideally it should populate the ephimeral node but issue here is it doesn't.

       

      Thanks
