To configure BlackBerry® Router high availability, you can configure a pool of two or more BlackBerry Router instances.

To configure a BlackBerry Router pool, you must add the identities of all BlackBerry Router instances to each BlackBerry® Enterprise Server that uses the same BlackBerry Configuration Database.

If you install two or more BlackBerry Router instances and a primary BlackBerry Enterprise Server loses its connection to the BlackBerry Router instance that it is using, it tries to connect to another BlackBerry Router instance in the pool. If the BlackBerry Enterprise Server can connect, it resends the service books to update the BlackBerry devices.
