ZeroTier bridge configuration will allow 2 (or more) LAN's in the same Zerotier network to be interconnected. For this example we will use two RUTX routers. Both of these routers should already have ZeroTier package installed and be connected to the ZeroTier Portal.

*From the '''''Bridge to''''' dropdown menu select '''''LAN'''''. This extends the network by forwarding traffic between LANs. Bridges operate at the data link layer and facilitate seamless communication between devices on different LAN segments
*From the '''''Bridge to''''' dropdown menu, select '''''LAN'''''. This option bridges The ZeroTier interface with the device's LAN interface, which extends the network and allows for Layer 2 communication via ZeroTier.

*Make sure to turn off '''Auto-Assign from range''' from the '''advanced section'''. This is because, when In ZeroTier network LAN bridging with Layer 2 bridge, managed IP addresses are not necessary because ZeroTier interfaces do not possess individual IP addresses. Instead, Layer 2 bridging allows for direct communication between devices using their local MAC addresses, eliminating the need for IP address management.
*Make sure to turn off '''Auto-Assign from Range''' in the '''advanced section'''. Since this is a Layer 2 bridge configuration, there is no need for IP addresses on the ZeroTier Interfaces and managed IPs. With Layer 2 bridging, devices communicate directly using their local MAC addresses, eliminating the necessity for IP address management.
*'''NOTE: Make sure to remove any Managed IPs that might have stayed when the Auto-assigned feature was turned on (by default, ZeroTier keeps it on).'''
*In the '''Advanced section → Managed Routes,''' add the LAN network route (in this case, 192.168.1.0/24), which ensures communication within the bridge. This allows devices in the ZeroTier network to communicate with devices on the LAN.

*In the '''Advanced section → Managed Routes''' add the LAN network route(in this case,192.168.1.0?24), this ensures connectivity between ZeroTier network and the local LAN. This allows devices in the ZeroTier network to communicate with devices on the local LAN.
*To ensure convenience and avoid any IP or routing conflicts, it is recommended to remove any other automatically assigned routes in ZeroTier. By doing so, you can prevent routing issues and ensure smoother communication within the LAN bridge network of 192.168.1.0/24 over the ZeroTier Network.
If everything was done correctly, you should be able to ping devices connected to separate routers. Let us test this by pinging a laptop connected to the second router (192.168.1.163) from a laptop connected to the first router (192.168.1.220):

'''Note:''' If you wish to add more routers to the bridged network, you should configure them according to the second router configuration.
