You can configure an IPv4-only, IPv6-only, or a dual mode (IPv4 and IPv6) Grid, but the configuration example uses IPv4 addresses. In this example, you configure seven NIOS appliances in a Grid serving internal DHCP and DNS for an enterprise with the domain name corpxyz.com. There are four sites: HQ and three branch offices. A hub-and-spoke VPN tunnel system connects the sites, with HQ at the hub. The distribution and roles of the NIOS appliances at the four sites are as follows:

  • HQ site (four appliances in two HA pairs):
    • HA Grid Master – hidden primary DNS server
    • HA member – secondary DNS server and DHCP server for HQ
  • Site 1 (two appliances in an HA pair): HA member – secondary DNS server and DHCP server for Site 1
  • Site 2(one appliance): single member – secondary DNS server and DHCP server for Site 2

Note: When adding an Infoblox appliance to an existing Grid, you must first check whether the Grid is running the minimum required software release of the appliance. For information, refer to the document, Minimum Required Release Software for Hardware Platforms, that was shipped with your product.


To create a Grid, you first create a Grid Master and then add members. The process involves these three steps:

  1. Configuring two appliances at HQ as the Grid Master. See Create the Grid Master.
  2. Logging in to the Grid Master and defining the members that you want to add to the Grid; that is, you configure Grid member settings on the Grid Master in anticipation of later joining those appliances to the Grid. See Define Members on the Grid Master.
  3. Logging in to the individual appliances and configuring them so that they can reach the Grid Master over the network and join the Grid. See Join Appliances to the Grid.

After creating the Grid and adding members, you use the Data Import Wizard to import DHCP and DNS data from legacy servers. See Import DHCP Data and Import DNS Data.
Finally, you transition DHCP and DNS service from the legacy servers to the Infoblox Grid members. See Enable DHCP and Switch Service to the Grid.

Cable All Appliances to the Network and Turn On Power
Cable the NIOS appliances to network switches. After cabling each appliance to a switch and connecting it to a power source, turn on the power. For information about installing and cabling the appliance, refer to the user guide or installation guide that ships with the product.

  1. At HQ and Site 1, connect Ethernet cables from the LAN1 and HA ports on the appliances in each HA pair to a switch, connect the appliances to power sources, and turn on the power for each appliance.

    Note: When connecting the nodes of an HA pair to a power source, connect each node to a different power source if possible. If one power source fails, the other might still be operative.

  2. At Site 2, connect an Ethernet cable from the LAN1 port on the single appliance to a switch, connect the appliance to a power source, and turn on the power for that appliance.

Create the Grid Master


Note: IPv6 addressing is fully supported on Infoblox Grid Masters, HA pairs and standalone HA pairs and appliances.
Examples in the sections of this chapter use IPv4.


Configure two appliances at HQ to be the two nodes that make up the HA pair forming the Grid Master.

  10. Click Finish.

When you click Finish, the Infoblox GUI application restarts.

Grid Master – Node 2

  1. By using the LCD or by making a console connection to the appliance that you want to make Node 2 of the HA pair for the Grid Master, change the default network settings of its LAN1 port to the following:
    • IP Address: 10.0.1.8
    • Netmask: 255.255.255.0
    • Gateway: 10.0.1.1
  2. In the login window, type 10.0.1.8 in the Hostname field.
  3. Log in using the default user name and password admin and infoblox.
  4. From the Grid tab, select the Grid Manager tab -> Members tab -> member check box.
  5. Expand the Toolbar and click Join Grid and specify the following:
    • Virtual IP of Grid Master: 10.0.1.10.
    • Grid Name: Enter corpxyz.
    • Grid Shared Secret: Enter Mg1kW17d.
  6. Confirm the configuration, and then on the last screen of the wizard, click Finish. The HTTPS session terminates, but the login window remains open.
  7. In the login window, type 10.0.1.10 (the VIP address for the Grid Master) in the Hostname field.
  8. Log in using the default user name admin and the password 1n85w2IF.
  9. To check the status of the two nodes of the HA Grid Master, navigate to the Grid tab, select the Grid Manager -> Members tab. This panel lists the Grid members. Check the icon in the Status column of the Grid Master. (green = the appliance has joined the Grid and is functioning properly; yellow = the appliance is in the process of joining the Grid; red = the appliance has not joined the Grid). You can also use the CLI command set network to join an appliance to a Grid. Check that the status indicators are all green in the Detailed Status panel.

During the joining process, an appliance passes through the following four phases:

  1. Offline – the state when a Grid member—in this case, the second node of the HA pair composing the Grid Master—is not in contact with the active node of the master
  2. Connecting – the state when an appliance matching a member configuration contacts the master to join the Grid and negotiates secure communications and Grid membership
  3. Synchronizing – the master transmits its entire database to the member
  4. Running — the state when a member is in contact with the master and is functioning properly

Note: Depending on the network connection speed and the amount of data that the master needs to synchronize with the member, the process can take from several seconds to several minutes to complete.


Define Members on the Grid Master

Before logging in to and configuring the individual appliances that you want to add to the Grid, define them first on the Grid Master. You can configure a Grid member in IPv4, IPv6, or a dual mode (IPv4 and IPv6), but the configuration example uses IPv4 addresses.

As an appliance joins a Grid, it passes through the following phases: Offline, Connecting, (Downloading Release from Master), Synchronizing, and Running.)


Note: Depending on the network connection speed and the amount of data that the master needs to synchronize with the member, the process of joining a Grid can take from several seconds to several minutes to complete.



The Grid setup is complete.

Import DHCP Data

The Data Import Wizard is a software tool that you can download from the Infoblox Support site to your management system. With it, you can import data from legacy DHCP and DNS servers to NIOS appliances. In this example, you use it to import both DHCP and DNS data to the Grid Master at 10.0.1.10, which then uses the database replication mechanism to send the imported data to other Grid members. In the wizard, you also specify which Grid members serve the imported data. The wizard supports various types of DHCP formats, such as the following:

  • ISC DHCP
  • Lucent VitalQIP
  • Microsoft
  • Nortel NetID
  • CSV (comma-separated values); you can also import IPAM data in CSV format In this example, all the DHCP data is in standard ISC DHCP format.

Importing DHCP Data for HQ and Site 2

  1. Save the DHCP configuration file from your legacy DHCP server at 10.0.2.20 to a local directory.
  2. Visit https://support.infoblox.com, log in with your support account, and download the Data Import Wizard. The Data Import Wizard application downloads to a container within a Java sandbox on your management system and immediately launches, displaying the Welcome page.

  4. Select Import to Infoblox Appliance, enter the following, and then click Next:
    • Hostname or IP address: 10.0.1.10
    • Username: admin
    • Password: 1n85w2IF
  5. Select the following, and then click Next:
    • What kind of data would you like to import? DHCP/IPAM
    • Which legacy system are you importing from? ISC DHCP
    • Which appliance will be serving this data? 10.0.2.10
  6. Type the path and file name of the DHCP configuration file saved from the legacy server, and then click Next.
    or
    Click Browse, navigate to the file, select it, click Open, and then click Next.
  7. In the Global DHCP Configuration table, double-click the Value cell for the domain-name-servers row, and change the IP addresses to 10.0.2.10.
  8. When satisfied with the data, click Import.
    You can view the status of the importation process and a summary report in the Data Import Wizard Log.
  9. To enable DDNS updates, log in to the Grid Master, from the Data Management tab, select the DHCP tab, expand the Toolbar and click Grid DHCP Properties.
  10. In the DDNS -> Basic tab of the Grid DHCP Properties editor, select Enable DDNS Updates.
  11. Save the configuration and click Restart if it appears at the top of the screen.
  12. To check the imported DHCP configuration file, from the Data Management tab, select the DHCP tab, -> Members tab -> 10.0.2.10 -check box. Expand the Toolbar and click View DHCP Configuration.
  13. In the DHCP configuration file, check that all the imported subnets are present, and navigate to the beginning of the file and check that you see the ddns-updates on statement. (If you see ddns-updates off, enable DDNS updates for the Grid as explained in steps 9-12.)

Importing DHCP Data for Site 1

  1. Repeat the steps in Importing DHCP Data for HQ and Site 2, saving the DHCP configuration file from your legacy DHCP server at 10.1.1.20, and importing it to the Grid Master at 10.0.1.10 for the member with IP address 10.1.1.10 to serve.
  2. Check the imported DHCP configuration file by logging in to the Grid Master and from the Data Management tab, select the DHCP tab -> Members tab -> 10.1.1.10 -check box. Expand the Toolbar and click View DHCP Configuration.

Importing DHCP Data for Site 3

  1. Repeat the steps in Importing DHCP Data for HQ and Site 2, saving the DHCP configuration file from your legacy DHCP server at 10.1.1.20, and importing it to the Grid Master at 10.0.1.10 for the member with IP address 10.3.1.10 to serve.
  2. After the importation process completes, check the imported DHCP configuration file by logging in to the Grid Master and from the Data Management tab, select the DHCP tab -> Members tab -> 10.3.1.10 -check box. Expand the Toolbar and click View DHCP Configuration.

Import DNS Data

Using the Infoblox Data Import Wizard, import DNS data from the legacy hidden primary server at 10.0.1.5 to the new hidden primary server at 10.0.1.10 (the Grid Master). There are three phases to this task:

  • Before Using the Wizard:
    • Save the named.conf file from the legacy server to a file in a local directory on your management system.
    • Enable the legacy server to perform zone transfers to the NIOS appliance.
    • Configure three name server groups for the Grid, and allow the Grid Master/hidden primary DNS server at 10.0.1.10 to receive DDNS updates from the Grid members at 10.0.2.10, 10.1.1.10, and 10.3.1.10. These members act as secondary DNS servers and DHCP servers.
  • Using the Wizard: Define the source, destination, and type of DNS data in the DNS configuration file (named.conf) that you want to import.
  • After Using the Wizard: Check the imported DNS configuration file.

In this example, all the DNS data is in BIND 9 format. The Data Import Wizard supports various types of DNS formats, such as the following:

  • BIND 4, 8, and 9
  • Microsoft
  • Lucent VitalQIP
  • Nortel NetID


Before Using the Wizard
You must set up the legacy server and Grid Master before using the Data Import Wizard.

Legacy Server

  1. Log in to the legacy name server at 10.0.1.5 and save the named.conf file, which contains all the DNS settings that you want to import into the Infoblox name server, to a local directory on your management system.
  2. On the legacy server, enable zone transfers to the NIOS appliance.

Infoblox Grid Master – DDNS Updates

  1. Log in to the Grid Master at 10.0.1.10, and from the Data Management tab, select the DNS tab -> Members tab -> 10.0.1.10 check box and select the Edit icon.
  2. In the Member DNS Configuration editor, select the Updates tab -> Basic tab and enter the following:
    • Select Override.
    • Allow updates from: Click the Add icon and select IPv4 Address. Enter 10.0.2.10 in the Name field of the new row.
  3. Click the Add icon again and add 10.1.1.10 and 10.2.1.10 as IP addresses from which you allow DDNS updates.
  4. Save the configuration and click Restart if it appears at the top of the screen.

Note: When all DNS servers are members in the same Grid, the members use database replication to synchronize all their data—including DNS zone data. You can change the default behavior so that Grid members use zone transfers instead. In this example, Grid members use database replication.


Infoblox Grid Master – Name Server Groups

  1. From the Data Management tab, select the DNS tab -> Name Server Groups tab.
  2. Click the Add icon to open the Add Name Server Group wizard.
  3. Enter the following:
    • Name Server Group Name: HQ-Group
  4. Click the Add icon and add the following:
    • Grid Primary: ns1.corpxyz.com; Stealth: Select this check box.
    • Grid Secondary: ns2.corpxyz.com; Grid replication (recommended): Select this check box.
  5. Click Save & New.
  6. Repeat steps 2 to 4 to create another group. Name it Site1-Group, and use ns1.corpxyz.com as the hidden primary server, ns3.site1.corpxyz.com as a secondary server, and Grid replication for zone updates.
  7. Repeat steps 2 to 4 to create another group. Name it Site2-Group, and use ns1.corpxyz.com as the hidden primary server, ns4.site2.corpxyz.com as a secondary server, and Grid replication for zone updates.

Using the Wizard

While progressing through the Data Import Wizard, you must define the source, destination, and type of DNS data that you want to import. You then make some simple modifications to the data and import it.

Defining the Source, Destination, and Type of DNS Data

  1. Launch the Data Import Wizard.
  2. After reading the information in the left panel of the welcome page, click Next.
  3. Select Import to Infoblox Appliance, enter the following, and then click Next:
    • Hostname or IP address: 10.0.1.10
    • Username: admin
    • Password: 1n85w2IF
      The Data Import Wizard Log opens in a separate window behind the wizard. Leave it open while you continue.
  4. Select the following, and then click Next:
    • What kind of data would you like to import? DNS
    • Which legacy system are you importing from? BIND 9
    • Which appliance will be serving this data? 10.0.1.10
  5. Select the following, and then click Next:
    • What BIND 9 DNS configuration file would you like to use? Click Browse, navigate to the named.conf file you saved from the legacy server, select it, and then click Open.
    • What type of BIND 9 DNS data do you want to import? DNS zone information and DNS record data
    • Where is the BIND 9 DNS record data? Zone transfer(s) from a DNS server; 10.0.1.5

The wizard displays two tables of data. The upper table contains global DNS server configuration parameters. The lower table contains zone configurations.
The Data Import Wizard Log presents a summary listing the number of views, zones, and DNS records in the configuration file.


Note: Only superusers can import A, AAAA, shared A, and shared AAAA records with a blank name. Limited-access users must have read/write permission to Adding a blank A/AAAA record in order to import A, AAAA, shared A, and shared AAAA records with a blank name, otherwise the import operation might fail. You can assign global permission for specific admin groups and roles to allow to import A, AAAA, shared A, and shared AAAA records with a blank name. For more information, see Administrative Permissions for Adding Blank A or AAAA Records.


Modifying DNS Data
While importing data from the legacy DNS server, you cancel the importation of global configuration settings, and apply the name server groups you created in Before Using the Wizard to the zones you want to import.

  1. In the Global DNS Configuration table, select all rows by clicking the top row and then SHIFT+clicking the bottom row.
  2. Right-click the selected rows to display the Set Import Options dialog box, select Do not import, and then click Apply.
  3. In the DNS Zones table, clear the Import check box for the default view.
  4. Select corpxyz.com, lab.corpxyz.com and all the corresponding reverse-mapping zones.

    Tip: You can use SHIFT+click to select multiple contiguous rows and CTRL+click to select multiple noncontiguous rows.

  5. Right-click the selected rows, and then select Set Import Options.
  6. In the Set Import Options dialog box, enter the following, and then click Apply:
    • Set Zone Type: No change
    • Set Import Option: No change
    • Set View: default
    • Set Member: HQ-Group master
  7. Select site1.corpxyz.com and all the reverse-mapping zones with 1 in the second octet in the zone name (1.1.10.in-addr.arpa, 2.1.10.in-addr.arpa, 3.1.10.in-addr.arpa, and so on).
  8. Right-click the selected rows, and select Set Import Options.
  9. In the Set Import Options dialog box, make the same selections as in 6, but choose Site1-Group master from the Set Member drop-down list.
  10. Similarly, select site2.corpxyz.com and all the reverse-mapping zones with 2in the second octet in the zone name.
  11. Right-click the selected rows, and select Set Import Options.
  12. In the Set Import Options dialog box, make the same selections as in 6, but choose Site2-Group master from the Set Member drop-down list.

Importing DNS Data

  1. Click Import.
    The wizard imports the global DNS parameters and zone-specific configuration settings from the named.conf file and performs a zone transfer of the data from the legacy server.
  2. Use the Data Import Wizard Log to monitor progress and review results afterward.
    The log lists all the zones that the wizard imports and concludes with a total of all the successfully and unsuccessfully imported zones.

    Note: If the wizard is unable to import a zone, an error message with an explanation appears in the log.

  3. To close the Data Import Wizard, click Exit. This closes the Data Import Wizard Log as well.

After Using the Wizard

After you import data, you must restart services on the Grid Master and delete the A records for the legacy servers from the corpxyz.com zone. You can also confirm that the imported data is correct and complete by checking the DNS configuration and the forward- and reverse-mapping zones.

  1. Log in to the Grid Master (10.0.1.10), select the Grid tab, expand the Toolbar, and then click the Restart Services icon.

    Note: When importing data through the wizard rather than entering it through the GUI, the Restart Services icon does not change to indicate you must restart service for the appliance to apply the new data. Still, restarting service on the Grid Master is necessary for the imported configuration and data to take effect.

  2. To remove A records for the legacy servers, from the Data Management tab, select DNS tab -> Zones tab -> corpxyz.com.
  3. Expand the Records section, select the following A records in the corpxyz.com zone, and then click the Delete icon: 
    1. ns1 (for 10.0.1.5)
    2. ns2 (for 10.0.2.5)
    3. ns3.site1.corpxyz (for 10.1.1.5)
    4. ns4.site3.corpxyz (for 10.2.1.5)
  4. Remove the respective A records for legacy servers from the site1.corpxyz and site3.corpxyz subzones.
  5. To check the imported DNS configuration file, from the Data Management tab, select DNS tab -> Members tab → 10.0.1.10 check box. Expand the Toolbar and click View -> View DNS Configuration.

    Note: If you do not see the imported DNS configuration file, make sure you enabled DNS and restarted services.

  6. Scroll through the DNS configuration log to check that each imported zone has an allow-update statement like the following one for the 10.1.10.in-addr.arpa reverse-mapping zone:

    zone "10.1.10.in-addr.arpa" in {

 …
allow-update { key DHCP_UPDATER; 10.0.2.10; 10.1.1.10; 10.2.1.10; };

};

Enable DHCP and Switch Service to the Grid

Finally, you must enable DHCP service on the three Grid members at 10.0.2.10, 10.1.1.10, and 10.2.1.10, and switch DNS and DHCP service from the legacy DNS and DHCP servers to them.

  1. Log in to the Grid Master (10.0.1.10)and from the Data Management tab, select the DHCP tab -> Members tab -> 10.0.2.10 check box. Expand the Toolbar and click Start.
  2. Repeat step 1 to enable DHCP on 10.1.1.10 and 10.3.1.10.

    Note: Start the DNS service, as described in Starting and Stopping the DNS Service.The Grid members are ready to serve DHCP and DNS, and send DDNS updates.

  3. Take the legacy DHCP and DNS servers offline.
