Would you be willing to help me with a test?

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.

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.
