So I’m thinking to move from bridged wireless network to routed. Now I have like 7 sites (2-3sectors/site), all linked daisychain/star topology… See attached example. In A there is linux server, now serving as NAT gateway / traffic shaper, with own created user management. User get IP from DHCP. With routed setup I can link F and G sites and make ring failover… As I know linux well, I thinking about tunnel vlans from all sites to linux server, this gives me separate access to sites and keep DHCP running. Vlans on some routed protocols (static, ospf, mpls?)… So the main question is, what posibilities are to implement this setup using OSPF or similar?
Star topology is a network topology which consists of a central node, to which all other nodes are connected. Your network is not a star topology.
You can implement ospf for routing between sites. For L2 communication the easiest would be to use eoip but mpls/vpls would give you the best performance.
Not sure about eoip on linux but vpls is certainly vendor independent.
Have you considered replacing your linux box with a router? A CCR1009 is enough to handle your scenario, will set you off by about $400 and you will no longer need to worry about compatibility issues.
If you’re using L2 connectivity just to make DHCP work you should look into DHCP relay. Then you could go L3 to the AP and still have one central DHCP server.
Thanks guys for answers. As I know for now(after lot searching), that vlans not possible on routed L3 network. Looked like easy and convenient way to manage network… So I will consider other known ways to do that, but allways looking for sweet spot
If you think about it, this makes sense right? Routing is a layer3 thing. VLANs are a layer2 thing. They’re completely different from each other.
That’s why you’d need VPLS or EoIP tunnels - because you’d use tunnels to carry the layer2 information across a layer3 network.
