Tasks

  1. Verifying members have recursion enabled.

  2. Creating a forward zone.

Task 1: Verifying recursion is enabled on members

You know the members ibns1 and ibns2 will be performing the forwarding. Please verify that these two members have recursion enabled, in order to forward to the remote server properly.

Task 2: Creating a forward zone

The private name space hr.techblue.io is hosted by ACME Corporation name server. The name server for hr.techblue.net is evocati.training.infoblox.com with the IP address 198.107.144.165. Please configure the Grid, so that members ibns1.techblue.net and ibns2.techblue.net will forward all DNS queries destined for hr.techblue.io to the correct destination.

 

Solutions

Task 1 Solution: Verifying recursion is enabled on members

Recursion must be enabled on DNS servers for forwarding to work. We need to verify that recursion is configured correctly

  1. Navigate to Data Management  DNS Zones

  2. Click Grid DNS Properties from the toolbar

  3. In the Queries tab, scroll down and verify Allow Recursion box is checked

  4. Check this configuration at the member level (Data Management DNS Members) as well.

  5. The DNS service may need to be restarted, but we can restart it after the next Task where we create the Forward zone.

Task 2 Solution: Creating a forward zone

  1. Lookup the IP address for evocati.training.infoblox.com (you can use the dig command in a terminal on jump-desktop)

  2. Under Data Management DNS Zones, click + dropdown and choose Forward Zone

  3. Leave the radio button set to Add a forward forward-mapping zone, and click Next

  4. For Name, enter hr.techblue.io

  5. Leave the remaining settings unchanged and click Next

  6. Select Use this set of name servers, click on the Add (+) icon

  7. For the Name Server Name, enter evocati.training.infoblox.com

  8. For the Name Server Address, enter the IP address we obtained in step 1.

  9. Check the box for Use forwarders only.

  10. Click Next

  11. In Step 3, select Use this set of name servers and click on the Add (+) icon

  12. Select ibns1.techblue.net from the name server list

  13. Click on the Add (+) icon again

  14. Select ibns2.techblue.net from the name server list

  15. Click Save & Close

  16. Restart Services from the notification tab

  17. The Zones window now displays the new hr.techblue.io forward zone
