9.3.1.2 Configuring AP#2
AP#2 can be configured the same as AP#1 with the following exceptions:
• Assign an IP Address to the LAN1 Interface different than that of AP#1
• Assign a higher Mesh STP Priority 50000 to the AP#2 LAN1 Interface.
NOTE In a typical deployment, each base bridge can be configured for a Mesh
NOTE Ensure AP#1 and AP#2 use the same channel for each 802.11a radio, or
STP Priority of 50000. In this example, different values are used to force
AP#1 to be the forwarding link since it's a small mesh network (of only
three APs) with AP within close proximity of one another.
the APs will not be able to "hear" each other over different channels.
