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)
