RE: Layer 2 based anycast - Kind like GLBP - Research

[Jean St-Laurent via NANOG <nanog () nanog org>]

Maybe a spine and leaf architecture could work for you. 

 

You could install 1 server per leaf or more. I believe this could achieve high-availability and load-balancing at layer 
2.

 

There is a kind of layer 3 overlay, but for the hosts this is transparent and it feels like a real pure layer 2. 

 

I would go that route as it is also a very common setup these days. It scales well horizontally and no active/passive. 
It’s just active/active/active/active…./active.
