This allows for extremely flexible implementation options with seamless physical-to-virtual integration. In addition, proposals are already in place for the next overlay evolution, in the form of Generic Protocol Encapsulation (GPE) and Network Service Header (NSH). 19 For now, VXLAN remains the de facto overlay protocol for data center deployments. Cisco Open Programmable Fabric With the introduction of VXLAN as a competent standards-based data center overlay solution, learning within a VXLAN network was still based on F&L semantics.
Consequently, from a redundancy or fault tolerance point of view, if that switch goes down, traffic to and from the downstream device or host is black-holed until the tree is recalculated. Network scale: In the age of cloud computing, significant constraints can be introduced as a result of having only a 4K network namespace, especially with the addressing and numbering for tenant networks. Even a medium-sized data center deployment can host several tenants, each of which might have a set of networks that summed together exceeds this limit.
