IP Public in cluster XL

[Diana_Carolina_]

Good afternoon, I need your help, at this moment I am in an implementation but the client has few public IPs to configure them in the Cluster, in this scenario you would need three public IPs, there is only one way of the cluster and the others Gateway IPs are private ?? This would affect if channel redundancy is required ?? I appreciate who can guide me with the procedure. Thank you very much

You do not need three public IPs for the external interfaces of the cluster.

RFC 1918 (private IPs) could be used for the cluster members with only one public IP assigned to the external vIP of the cluster.
