Cause: To add an alias to a FQDN for GEO load balancing
Resolution:

Before adding a CNAME, please note that the following validation is in place for CNAME records:

  • There cannot be duplicates.

  • CNAMEs you add must be part of the domain (must be a child of the FQDN and not the same as the FQDN).

  • CNAMEs must be a domain name (no IP addresses).

  • FQDNs cannot be added if it already exists as a CNAME.

  • Zones cannot be added if it already exists as a CNAME.

  • A CNAME cannot be added if an FQDN with the same name already exists.

  • A CNAME cannot be added if a Zone with the same name already exists.

The following steps cover how to add a CNAME:

1. Navigate to the LoadMaster's Web UI > Global Balancing > Manage FQDNs > Locate the FQDN to modify > Modify

2. Additional records > Set Record Type to CNAME and enter the CNAME in the Data field > Add as shown below:
