You can create a cluster of on demand routers. The cluster that is created is a static cluster.
You might consider clustering on demand routers when you are integrating the Session Initiation Protocol (SIP) on demand router (ODR) with Load Balancer for IBM WebSphere Application Server.
You might consider creating a cluster of HTTP ODRs to administer all of the ODRs at one time. If you do not create a cluster, you must administer each ODR individually.
You placed multiple on demand routers in a cluster.
To modify the settings, such as the action type and rule expression, of an ODR cluster, use the wsadmin tool to complete administrative tasks at the cluster level. For more information, see Rules for ODR routing policy administrative tasks and Rules for ODR service policy administrative tasks .
