This topic describes advanced core group bridge configurations.
Advanced configuration scenarios
Communication between core groups that are in the same cell
Communication within the cell and outside of the cell
Following is an example of 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, access_point_group_xyz, 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 sample shows the relationship between bridge interfaces and peer ports for the communication between cell_x and cell_z. In cell_x, there are two bridge interfaces defined. In cell_z, there is a peer access point for x_core_group_ap_2 that has peer ports defined that correspond to the bridge interface information that is defined in cell_x.
As a result, core_group_x , core_group_y and core_group_z can communicate with each other.
Communication between core groups across different networks
Communication between core groups using a proxy peer access point
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.
