Project #35 - Adding VLANS to the FLINT1 and FLINT2 routers

I have finally come to the point where I need to setup VLANs on the FLINT routers in my network.  I have noted for some time that people have problems with setting up VLANs on GL-iNet routers in general.  I mainly want to do this so that I can have some vlans that are outside of my normal Edgerouter-12 controlled space.  This would also enable me to get more into the fine tuning of these routers.  I can see having a couple of guest vlans on each router which would connect over iBGP.  I am currently reading a book on the ins and outs of GL-iNet that might give me some better information on how to do this, however at the moment it seems to be more of a word salad than a how to book.

I also need to be careful to document the entire process so that I can reproduce it.  To that end I will document the process in the RedNotebook app.  I intend on noting differences between the FLINT1 and FLINT2 setups. The main changes should be limited to one or two vlans on each router:

• On FLINT1 I will add two VLANs; Guest1 and Arbitrary1 that will not have access to the basic vlan
• On FLINT2 I will add two VLANs; Guest2 and Arbitrary2 that will not have access to the basic vlan
• The setup should be able to be altered to accommodate iBGP or VXLAN in the future (or any other items I might want to experiment with)

State of the Network in June 2025

I just recently changed my connections between the living room and the back bedroom.  Now I have a flat cable going between the FLINT 1 router in the living room to a switch in the back bedroom where I have connected both the PiHole Raspberry Pi and the switch originally in the living room to my rack.  In this way, I now do not have any vlans accessible in the living room.  I basically decided that all of my activities should be done in the back bedroom where I have my rack equipment.  I also now have the TCL TV connected directly to the FLINT 1 router.  I may still try to do a BGP from the FLINT 2 router in the back bedroom to the FLINT 1 router in the living room, but I have plenty of time to tinker before that happens. I do have some thoughts about how I might change things in the future:

• Complete the task of setting up a Certificate Authority in the HomeLab=
• Add VLANs to the FLINT2 router
• Arrange the power so that the FLINT2 router can remain on if I shutdown the Rack
• Alter the way that I connect my laptop to the network so that it remains connected at all times on the correct VLAN
• Implement the PiHole to give out DNS and DHCP IPs within the HomeLab
• Work up some 3D printed components to stage the remaining Raspberry Pis external to the Rack, but still be present within the HomeLab
• Work up the use of my STREAM deck to issue MQTT messages for HomeLab control
• Spin up a file server on the HomeLab
• Finish setting up the Raspberry Pi display/controller; connected via Tailscale
