Increasingly coming to the view that BGP-EVPN is a big deal. Neither vendors or customers can imagine their networks without a 30 year old routing protocol so this is the half-pregnant, half-arsed solution that seems likely to gain widespread adoption.
You can mangle BGP configuration with an application and call it SDN. Heck, IXPs have been doing that for a decade so its not new.
Welcome to networking where “its not new” is the byline for SDN.
Coming soon with Cumulus Linux 3.2: EVPN – Cumulus Networks Blog: “Can you summarize the benefits of deploying EVPN?
Cumulus EVPN provides many benefits to a data center, including:
Controller-less VXLAN: No controller is needed with EVPN, as it enables VTEP peer discovery through BGP.
Scale and Robustness: EVPN uses the standard BGP routing protocol for the control plane. BGP is a mature well-known protocol that powers the internet. For data centers that already run BGP, this involves just adding another address-family.
Fast convergence/mobility: The BGP EVPN address family includes features to track host moves across the datacenter, allowing for very fast convergence.
Multi-vendor interoperable: Since EVPN is a standard, it will be interoperable with other vendors that adhere to the standard.
Support for Active/Active VxLAN: Cumulus EVPN supports host redundancy to switch pairs with an MLAG configuration.
Multi-tenancy: Cumulus EVPN supports VXLAN tunnel separation”
