The core group bridge service can be configured for communication between core groups. A core group is a statically defined component of the high availability manager. To configure communication between core groups, use an access point group. An access point group is a collection of core groups that communicate with each other.

Review the following topics before you configure a core group bridge service:

• Core groups (high availability domains)
• Creating a new core group (high availability domain)
• Configuring communication between core groups that are in the same cell

Overview

You must configure the core group bridge service whenever two or more core groups are configured in the same cell. You can also configure the core group bridge to share traffic among core groups that are in different cells. Configure the core group bridge to communicate between cells only when the service is required by another WebSphere Application Server component. By configuring the core group bridge service, the availability status of the servers in each core group is shared among all the configured core groups. You can configure core groups to communicate in the following ways:

Procedure

• Use the core group bridge for communication between core groups that are in different cells. Configuring this type of communication is the most common core group scenario. You can configure each cell to communicate with one or more other cells.

• Use advanced configurations. You might need to configure core group communication between core groups that are in the same cell, that communicate across different networks, or that use a proxy peer.
