Abstract
A network device is configured to associate a tenant of a plurality of tenants with a virtual routing and forwarding (VRF) instance of a plurality of VRF instances. The network device receives a packet comprising metadata specifying a tenant identifier for the tenant. The network device identifies, based on the tenant identifier specified by the metadata, the VRF instance associated with the tenant. The network device retrieves one or more routes from a routing information base (RIB) of the VRF instance associated with the tenant and forwards the packet toward a destination via the one or more routes.
