...
- Define all the static members involved in the deployment plan for each node.
- Use a reference "NextInterceptor" in interceptor configurations to chain interceptor together as you can see the configurations of DisableMcastInterceptor and TcpPingInterceptor in the sample below. You can control how the client requests are processed by arranging the order of the interceptor chain.

- Use a reference "NextStaticMember" in the second and subsequent StaticMember definitions, but not the last, to chain multiple static members.

See the following deployment plan snippet as an complete example of setting up application-scoped unicast clustering with more than two nodes.

Where
- IPAddress1 is the IP address or host name of current static member.
- TCP_port1 is the TCP port on the current node to listen for session replication data from other static members.
- IPAddress2 is the IP address or host name of the second static member.
- TCP_port2 is the TCP port on the second static member to listen for session replication data from other static members
- IPAddress3 is the IP address or host name of the third static member.
- TCP_port3 is the TCP port on the third static member to listen for session replication data from other static members
