Configuring the multi-cluster routing policy

In order to configure the on demand router (ODR) to route requests to a generic server cluster, you must configure a multi-cluster routing policy (MCRP) on each ODR. This allows the ODRs in one cell to send requests to a remote cell in the case that no application servers are available in the local cell.

About this task

Configure a multi-cluster routing policy (MCRP) on each ODR, in all cells, in order to configure the on demand router (ODR) to route requests to a generic server cluster. To configure all ODRs in each cell, complete the following steps:

Procedure

  1. Servers > On demand routers > ODR_name > On demand router properties > On demand router settings > Custom properties > New. $<applicationName> is optional. If not specified, this rule applies to all traffic sent to this ODR. If specified, it only applies to traffic destined for the application with the name <applicationName>.
  2. For the property name, type MCRP@<thisCellName>$<applicationName>.
  3. For the property value, type failover@<thisCellName>$<PrimaryDynamicCluster>,<thisCellName>$<GSCName>. This tells the ODR to first attempt to send traffic which matches this MCRP rule (based on the application name specified in Step 2, if any) to the local dynamic cluster of application servers that are in this cell. If none of the local application servers are available, it will failover to the generic server cluster specified (which is the ODRs in the other cell, which will then route the traffic to the application servers local to that cell).
