Configure VLAN Raspberry PI 4

I have flashed my Raspberry PI 4 to run OpenWRT.

I have configured the LAN and WAN connections. I want to create a separate subnet for my servers.
I tried using the wiki and came up with the below settings. The issue is when i try setting the IP address in the server , it is not resolving any connection to the Router or internet.
Currently when i ping the interface from my host it works as shown below

        option ula_prefix 'fd2c:576a:a0b1::/48'

  1. See switch configuration in LuCI.
  2. Give total /etc/config/network, does it contain switch section?

The RPi4 doesn't have a switch.

How are the devices connected to the RPi4? Directly? Managed switch? How are they obtaining an IP?

Create vlans on the built in Ethernet with eth0.1 eth0.2 etc. Once you start doing that, all packets must be tagged. It does not work to leave anything attached to "plain" eth0 and try to mix tagged and untagged on the same cable.


The devices are connected via unmanaged switch

They are obtaining IP from the DHCP server on the Raspberry Pi 4

How do I create vlans on the built in Ethernet with eth0.1 eth0.2? and how do i tag them?

Tagged VLANs require a (at least smart-)managed switch to be processed correctly. How unmanaged switches deal with tagged packets is undefined, they may let them pass, drop them randomly or serve them as a dog's dinner.
