Configure GEO Clusters with HA

If Global Server Load Balancing (GSLB)/GEO is being used in the environment, there are unique configuration requirements for setting up clusters. This section outlines the configuration and the steps can be modified based on the environment.

Configure GEO Clusters with HA IP Addresses

In this example, there will be two HA Pairs of LoadMasters and two standalone LoadMasters included in the GSLB environment. The steps will be the same if more or less units are in the environment.

To configure clusters of HA IP addresses between two HA pairs and two standalone systems, follow the steps below.

On HA pair 1, complete these steps:

1. Log into the Active LoadMaster in the HA pair.
2. In the main menu, go to Certificates & Security > Remote Access.

   

3. Enter the IP addresses of the ILBs in front of the HA pair of LoadMasters and the IP addresses of both standalone LoadMasters in the Remote GEO LoadMaster Access text box and click Set GEO LoadMaster access.
4. Enter the IP addresses of the ILBs in front of the HA pair of LoadMasters and the IP addresses of both standalone LoadMasters in the GEO LoadMaster Partners text box and click Set GEO LoadMaster Partners.
   Note: For the GEO LoadMaster Partners field - you do not need to specify the IP address (ILB IP Address) of the current LoadMaster you are connected to.
5. Reboot the Active LoadMaster.
6. Log into the new active LoadMaster.
7. In the main menu, go to Certificates & Security > Remote Access.
8. Re-enter the IP addresses of the ILBs in front of the HA pair of LoadMasters and the IP addresses of both standalone LoadMasters in the Remote GEO LoadMaster Access text box and click Set GEO LoadMaster access.
9. (Optional) Reboot the system again to get the original LoadMaster as active.

Repeat these steps on HA pair 2 and on the two standalone LoadMasters.

Then, create the GEO clusters with the TypeRemote LM using the IP addresses of the ILBs in front of the HA pairs and the IP addresses of both standalone LoadMasters. This only needs to be performed on one system as changes will be replicated to the other partner systems configured in the prior step.

1. In the main menu, go to Global Balancing > Manage Clusters.

   

2. In the IP address text box, enter the LoadMaster IP address.
3. Enter a Name for the cluster and click Add Cluster.
4. Click Modify on the relevant cluster.

   

5. Select Remote LM in the Type drop-down list.

Repeat these steps to add the remaining HA pair and on the two standalone LoadMasters.

Here are some example IP addresses for the scenario outlined above (involving two HA pairs and two standalone systems).

Here is an example configuration based on the scenario outlined above (involving two HA pairs and two standalone systems).

The IP addresses colored as red above correspond to the particular unit mentioned in the Unit column.
