Abstract
Methods, systems, and devices map an arbitrary number of Virtual Routing and Forwarding (VRF) instances to an Ethernet Virtual Private Network (EVPN) instance (EVI) of a leaf and spine network. For example, a spine network device executes a primary EVI to provide an EVPN to a plurality of leaf network devices, each leaf network device executing a secondary EVI to provide a plurality of network virtualization overlays to tenants of the network. The primary EVI is associated with a primary VRF instance, and each secondary EVI of the plurality of secondary EVIs is associated with a secondary VRF instance of a plurality of secondary VRF instances. The spine network device defines mappings between routes within the primary VRF instance and routes within each secondary VRF instance. The spine network device translates, based on the one or more mappings, network traffic between the primary EVI and the plurality of secondary EVIs.
