IP Tunnels
Primary LAN
home subnet
Secondary LAN
remote subnet
A non-root access point can concurrently receive hello messages on its Ethernet port, its
radio port, and its IP tunnel port. However, an access point can use only one port to
attach to the network. Port priorities are structured so that an Ethernet connection is
always selected first and an IP tunnel connection is always selected before a radio
connection.
Setting the secondary LAN bridge priority to zero disables the bridging of wireless
traffic to remote IP subnets. It allows end devices that are connected to access points on
a remote IP subnet to communicate with hosts on the home subnet without bridging
wireless traffic to the remote IP subnet. This is always done for IP communication since
the wireless traffic is always from the home subnet and not from the remote subnet. The
secondary LAN bridge priority will allow you to select the bridging mode for non-IP
traffic such as NNL.
