摘要： In some examples, a computing device comprises a first service function instance to apply a service function and a service function forwarder to: receive a first layer 3 routing protocol route advertisement that includes service function instance data for a second service function instance, the service function instance data indicating a service function type and a service identifier for the service function instance; receive a second layer 3 routing protocol route advertisement that includes service function chain data for a service function chain, the service function chain data indicating a service path identifier and one or more service function items; and send, to the second service function instance and based at least on determining a service function item of the one or more service function items indicates the second service function instance, a packet classified to the service function chain.

摘要： Techniques are disclosed for scalable virtualization of tenants and subtenants on a virtualized computing infrastructure. In one example, a first controller for the virtualized computing infrastructure configures underlay network segments in the virtualized computing infrastructure by configuring respective Virtual Extensible Local Area Network (VXLAN) segments of a plurality of VXLAN segments of a VXLAN in a switch fabric comprising network switches. Each VXLAN segment provides underlay network connectivity among a different subset of host computing devices of the virtualized computing infrastructure to enable orchestration of multiple tenants in the VXLAN. A second controller for a first subset of the host computing devices has underlay network connectivity through operation of a first VXLAN segment. The second controller configures overlay networks in the first subset of the host computing devices to enable orchestration of multiple subtenants in the first subset of the host computing devices.
