EVPN and VXLAN don’t seem very open? What kind of FUD is that – these are both standards that have been released via the IETF, the same way IPv4, IPv6, BGP, IS-IS, OSPF, and all the other protocols that we use are defined. IETF is as open as it gets. More to the point – how is Calico open? I can go read the specification for EVPN and VXLAN easily, where is the specification for Calico? If it’s such a good idea, why aren’t they participating in the IETF towards standardization?

And not very “cloudy”? Project Calico is about as far as you can get from a “cloud” as you can get. Inability to handle overlapping IP space and provider coordinated addressing? Is this an early 2000s colo or a modern “cloud” solution? And the solution to these problems is a kludge like 464XLAT when you’re talking about things like “elegance”?

Calico has some good ideas, like router in the hypervisor, but how is that different from VXLAN with the hypervisor being the NVE that controls VNIs?

I will take a look at Project Calico. Thanks for the pointer.

It doesn’t seem very cloudy or open that the solution to the VLAN scaling problem is to build a new protocol that needs specific Cisco hardware to implement. Certainly BGP is the way to go — it has years of reliability at the largest scale behind it and the idea of VMs coming online and being announced to the network via BGP is a very elegant one. However, that elegance should flow naturally throughout the fabric, and not need custom hardware.

Project Calico (projectcalico.org) is doing work in this area already and is open source to boot. Well worth a look.
