Figure 1-3: Point-to-Multipoint Configuration
Multipoint Mode (Central AP)
•
Two or more Central Access Points in the same Point-to-Multipoint configuration. In
this configuration, up to six Access Points are configured to communicate with the
same Central Access Point. You can configure one or more of those six Access Points
as a Central Access Point to communicate with up to five additional Access Points.
This configuration requires Wireless Relay to be enabled.
In Figure 1-4, Building A is the Central Access Point for Buildings A1 through A5 and
Building B. However, Building B is also the Central Access Point for Buildings A and
Building B1 through B5. You could expand this one further by making Building B3 a
Central Access Point for five other buildings, although adding additional hops may
decreases network performance.
To avoid bridging problems, do not configure an Access Point as an Endpoint for more
than one Central Access Point. In Figure 1-4, you would not configure Building B1 as
an Endpoint to communicate directly to Building A.
Figure 1-5 provides examples of configurations that cause network loops.
