The figure above shows all the neighbors that we managed to contact via OSPF, as we can see, routers with addresses 10.0.0.2, 10.0.0.3 and 10.0.0.4 neighbor on the eth0.3 interface, that is, the VPLS interface.

While the routers are 172.23.0.10, 172.23.0.30, 172.23.0.50 via the ztbto4jk6k interface, that is, via the Zerotier interface.

We also received default routes (0.0.0.0/0) from the routers on the back side, which will allow us to have backup internet connections in case the LTE connection on the site drops.

Finally route trace test. Connect client(you notebook) to router, and get address via DHCP, in test we see what computer get address 192.168.200.236 and we make tracert to server with another addresses ( 10.127.0.254 )

If we make trace we see all hops, Gateway 192.168.200.1 on side 192.168.200.1, VPLS interface routers on side 10.127.0.1/24 and last hop its endpoint (10.127.0.254)
