This topic describes advanced core group bridge configurations. These configurations are not performed as often as the typical core group bridge between core groups that are in different cells.
The most common core group bridge configuration is between two core groups that are in different cells on a single network. See Core group communications using the core group bridge service for more information about this common scenario. The scenarios that are described in this topic are for advanced configuration situations.
The following example illustrates a configuration between three core groups that are in three different cells. Each cell has one access point group for communication between core groups in the cell. Each cell also has a defined access_point_group_xyz access point group, which contains one core group access point group for the core group that is in the cell, and one core group access point for each of the core groups in the other two cells.
The following example shows the relationship between bridge interfaces and peer ports for the communication between thecell_x cell and the cell_z cell. In the cell_x cell, two bridge interfaces are defined. In the cell_z cell a peer access point exists for the x_core_group_ap_2 core group access point with peer ports defined that correspond to the bridge interface information that is defined in the cell_x cell .
As a result, the core_group_x , core_group_y and core_group_z core groups can communicate with each other.
Use a proxy peer when the core groups cannot directly communicate. The two core groups must have access to a single core group that can pass information between the two core groups. To understand what a proxy peer access point does, consider a connecting flight when flying on an airplane. To fly from Pittsburgh to London you first have to fly to New York City, where you change planes and then fly to London. New York City is the proxy peer access point for London.
