Abstract
A switch fabric has a plurality of leaf switches, each leaf switch having a local tenant identifier (LTID) table, a local forwarding information base (LFIB) table, and a forwarding engine coupled to the LTID table and LFIB table. Each leaf switch has downlink ports operative on VLAN packets such as those generated by Container/Virtual machines (CVM), each leaf switch also having a reconfigurable uplink port for transmission and reception of VxLAN packets formed from VLAN packets which have a destination address which is not local to a particular leaf switch. The uplink ports are coupled to the leaf ports of one or more spine switches, each spine switch having a Global Forward Information Base (GFIB) table slice coupled to a VxLAN forwarder which receives VxLAN packets, de-encapsulates them and uses the GFIB table slice to form new VxLAN packets transmitted to a different leaf port.
