Our new DC is EVPN on top of VXLAN, and one of our newest building has EVPN/VXLAN capable access switches too. Our campus/rest of the core is done with MPLS capable switches. I'd like to see us to transition to full EVPN/VXLAN fabric but the other networking guy who has something to say about this has a long ISP background so he prefers MPLS. However we do not use any TE/FRR features and not many people now how to debug MPLS networks if we had any issues. So far we haven't had any that would have been related to the MPLS part so it's quite hard to convince migrating to EVPN/VXLAN fabric would make sense :)
So any other benefits of going towards EVPN/VXLAN in the LAN side too, besides just having one set of protocols and not both MPLS and EVPN/VXLAN there? Currently the switches we use for MPLS are cheaper than the ArubaOS-CX switches with same amount of ports so the price point isn't one reason.
On the EVPN/VXLAN downsides are there any issues running something like 1500-2000 switches in the same EVPN/VXLAN fabric? Or should we somehow try to split the fabric to smaller parts? Our current MPLS setup is just VLANs from the access switches to the "PE switch" which is part of the MPLS network and the access switches are just very simple switches. So the MPLS network does not have that many devices doing routing and MPLS.
Thanks for any ideas!
