You need to set the root priorities and secondary LAN bridge priorities
for the bridge on the primary LAN and for the bridge on the secondary
LAN:
On the primary LAN bridge, set the root priority to a number that
is greater than the root priority of the secondary LAN bridge. The
access points will not form a point-to-point bridge if the primary
LAN bridge has a lower root priority than the secondary LAN
bridge.
On the secondary LAN bridge, set root priority to 0 and the
secondary LAN bridge priority to a number other than 0.
You may also need to adjust the flooding parameters. Here are some
recommendations:
If there are no end devices on the secondary LAN, the bridge on
the secondary LAN can use the default flooding settings. The
Secondary LAN Flooding parameter is disabled.
If there are end devices on the secondary LAN, the bridge on the
secondary LAN should have Secondary LAN Flooding parameter
set to Multicast. If you also want unicast flooding, you can set this
parameter to Enabled.
If there are end devices on the secondary LAN and the end devices
communicate with end devices on another secondary LAN, the
root access point should have its Multicast Flooding parameter
set to Universal. This setting ensures that all ARP requests and
multicast traffic is distributed through a second or third hop.
To install a point-to-point or a point-to-multipoint bridge
1. Follow the instructions Using One Access Point in a Simple
2. Configure the LAN ID. For help, see Configuring the Spanning Tree
3. (802.11b) Configure the station radio in the point-to-point bridge on
the secondary LAN.
