Preparing for cluster peering
Before creating a cluster peering relationship, you must verify that the time on each cluster is synchronized with an external Network Time Protocol (NTP) server, and determine the subnets, ports, and passphrases that you want to use.
Identify the subnets, IP addresses, and ports that you will use for intercluster LIFs.
By default, the IP address is automatically selected from the subnet. If you want to specify the IP address manually, you must ensure that the IP address either is already available in the subnet or can be added to the subnet later. Information about subnets is available in the Network tab.
The following table assumes that each cluster has four nodes. If a cluster has more than four nodes, you can record the ports on another piece of paper.
| Cluster A | Cluster B | |||
|---|---|---|---|---|
| IP address | ||||
| Node 1 port | ||||
| Node 2 port | ||||
| Node 3 port | ||||
| Node 4 port | ||||
