Introduction:
When creating a multisite cluster, each site may have a VIP address assigned. In such an environment it may occur that, by error, two of the sites  have the same VIP (Virtual IP) address defined. This is not allowed and it causes issues
Question:
Why do my cluster sites get immediately unsynchronized after I synchronize them?
Environment:
Any hardware or software appliance running PAM server 2.8 and above in a multisite cluster environment.
Answer:
The most likely cause for this problem to occur is having two different sites with the same Virtual IP (VIP) address, which must be unique for each cluster site.

Review the cluster configuration making sure that all the defined cluster sites have a different VIP address.
