Configure communication between core groups that are in the same cell

Use this task to configure communication between core groups that are in the same cell.

 

Before you begin

Configure two core groups with application servers that are in the same cell. For more information about when and how to configure multiple core groups, see Creating a new core group. Any time you configure multiple core groups that are in the same cell, you must configure communication between the core groups.

 

Overview

Each core group has one or more defined core group access points. A core group access point is a collection of network entry points for the core group. The network entry points that are in a core group access point are called bridge interfaces. An application server that hosts the bridge interfaces is called a core group bridge server.

To configure communication between core groups, define an access point group. An access point group defines the core groups that can communicate with each other. Each access point group has one core group access point for each core group. Select one or more servers to be core group bridges, and define a bridge interface for each server.

See Core group communications using the core group bridge service for more information about the core group bridge service.

 

Procedure

1. Configure an access point group to define the core groups that need to communicate. An access point group contains the core group access points for the core groups that need to communicate. Core group access points define the set of servers that provide access to the core group. To configure communication between core groups that are in the same cell, one can choose an existing access point group or create a new access point group. To create an access point, complete the following steps:

   1. In the administrative console, click Servers > Core groups > Core group bridge settings > Access point groups > New.

   2. Enter a name for the access point group that is unique within the cell.

   3. Add core group access points to your access point group. Choose any available core group access points for the core groups that need to communicate in the cell. A default core group access point is created whenever a core group is created. The access point group that you create must have a core group access point for each core group in the cell.

    

   Restriction

   Do not add any peer access points. Add peer access points only if you are configuring communication with a core group in a different cell. If we need to communicate with core groups that are outside of the cell, create another access point group that has one core group access point and one or more peer access points. See Configuring communication between core groups that are in different cells for more information. If you use an existing access point group, choose an access point group that does not have peer access points. To configure an existing access point group, perform the following steps:

   1. In the administrative console, click Servers > Core groups > Core group bridge settings. Your current configuration with any existing access point groups is displayed.

   2. Verify that the access point group does not have any peer access points. Peer access point groups are used for communication between core groups in different cells. Click the access point group you want to configure and ensure that no peer access points are listed.

   3. Click Access point groups > access_point_group_name > Core group access points.

   4. Add core group access points to your access point group. Choose any available core group access points for the core groups that need to communicate. The access point group you create should have a core group access point for each core group in the cell.

2. Create bridge interfaces for each core group access point. The bridge interfaces that you add provide access to the core group. Create at least one bridge interface for each core group access point. To back up your configuration, you should configure two or more bridge interfaces for each core group access point. If a core group has multiple core group access points, each core group access point must contain the same number of bridge interfaces for the same set of servers. To configure bridge interfaces, perform the following steps:

   1. In the administrative console, click Servers > Core groups > Core group bridge settings > Access point groups > access_point_group_name > Core group access points.

   2. Click a core group access point in the access point group. Click Show Detail.

   3. To create a new bridge interface, click Bridge interfaces > New.

   4. Select a node, server, and transport channel chain combination for the bridge interface. Click OK. All the core group access points in the access point group must have transport channel chains with the same port name. The transport channel chain can be the DCS or DCS-secure channel chains that are created for the DCS_UNICAST_ADDRESS transport chain.

   5. Consider creating at least two bridge interfaces for each access point. If one bridge interface fails, the other can still be active.

   6. Repeat these steps to create bridge interfaces for each core group access point in your access point group.

 

Result

The core groups that are in the same cell and configured in an access point group can communicate.

 

Example

In cell_x, there are three core groups: x_core_group_1, x_core_group_2, and x_core_group_3. Each core group already has a core group access point. The following image shows an access point group between the core groups in cell_x and an example of the configuration in the administrative console.

Perform the following steps to configure communication between the three core groups in cell_x:

1. Create an access point group named x_access_point_group. Add a core group access point to the access point group for each core group that is in the cell. In this example, add x_core_group_ap_1, x_core_group_ap_2, and x_core_group_ap_3 to x_access_point_group.

2. Create bridge interfaces for each core group access point. The following diagram shows the bridge interfaces for x_core_group_ap_2:

   Create two or more bridge interfaces for each core group access point.

By creating an access point group and adding all core groups in the cell to the access point group, you enabled communication between all the core groups that are in cell_x.

 

What to do next

One can configure this cell to communicate with core groups in other cells. See Configuring communication between core groups that are in different cells and Configuring core group communication using a proxy peer access point for more information.
