Best Performance GRE vs EVPN/VPLS over IP/MPLS

[Erico Verissimo]

Hello all,

Let´s say I need to connect three data centers by ISP's IP/MPLS network. From the point of view of performance, without regard the physical links, What is the best technology that I should use GRE or VPLS?

Hello,

EVPN is clearly the best performing technology, generally speaking. The doc below discusses this in detail. GRE has been around for a long time and is available even on the lowest end platforms, while EVPN is not (and also requires BGP).

So the technological development is:

GRE --> VPLS --> EVPN

If equipment is not the issue, EVPN would be your choice.
