Ethan,
What you probably want to look at if the routers are going to be MikroTik is deploying VPLS over EoIP - we've done this a lot as a way to extend a provider MPLS network to deliver private services over standard Internet links. MPLS requires layer 2 so that it can put labels between the L2 and L3 headers which is why you'll need EoIP underneath. Then, you can deploy VPLS on top of LDP/OSPF which is multipoint and comes with inherent loop protection via split horizon. You'll need a full mesh of EoIP tunnels between sites and then you can turn on OSPF/LDP/VPLS. Also be mindful of your 1500 byte MTU limit and either plan to fragment or limit MSS for TCP accordingly. VPLS normally requires an MTU of 1530 so you'll lose some in the overhead of EoIP and VPLS. What you need to be aware of if you've never deployed an extended L2 domain is that site to site performance may not be quite as good as a routed network depending on what apps need to be available, so things like AD, File Shares, etc may not run as fast as they will on a routed network. You might want to setup a basic test for the applications you need to deliver before going down the road of a full VPLS deployment.

Dee via Mikrotik-users Sent: Tuesday, December 13, 2016 10:00 AM To: Mikrotik Users Subject: [Mikrotik Users] MPLS/VPLS/EoIP/etc. I am kind of new to the idea of have LANs span across WANs. A very basic idea I'm trying to accomplish is to have 3 sites that can share a L2 network without having to route (as far as the internal devices can tell). Also I don't own any of the routers in between. Like for example, one site is Level3 Fiber, one site is Charter 60x4, one site is 3 meg DSL. (don't get hung up on that part) What are some good ideas for this. Can't find a similar scenario anywhere. Would appreciate any input. -- This message has been scanned by E.F.A.
