Please read the following requirements and recommendations before you set up the redundant License Managers:
Note that redundant License Manager pool is not supported when Link Local addresses of the License Managers are used.
When a supported server-grade Windows machine (such as, Windows Server 2003 and 2008) is used as a client with firewall settings “on,” communication with License Manager on IPs other than the one at index 0 does not succeed. To overcome this, add the IP corresponding to the index 0 NIC to unblock responses.
