Forwarding tables for virtual networking devices

A system comprising:

• one or more processors;
• and
• a computer-readable storage medium having stored therein instructions which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• identifying virtual machines hosted on a local host associated with a switch, the switch comprising a virtual tunnel endpoint associated with an overlay network;
• generating a forwarding table for the switch and populating the forwarding table only with local entries comprising bindings or entries for the virtual machines hosted on the local host;
• and
• adding a default route in the forwarding table pointing to one or more devices running a forwarder function that is configured to handle non-local traffic relative to at least one of the switch and the local host, the forward function is implemented on another network different from the overlay network, and resides on a network fabric connected to the overlay network via the switch;
• and
• updating the forwarding table only based on updates to the virtual machines hosted on the local host or addition of new virtual machines hosted on the local host.

A non-transitory computer-readable storage medium having stored therein instructions which, when executed by a processor, cause the processor to perform operations comprising:

• identifying virtual machines hosted on a local host associated with a switch comprising a virtual tunnel endpoint associated with an overlay network;
• generating, via a processor, a forwarding table for the switch and populating the forwarding table with local entries comprising bindings or entries for the virtual machines hosted on the local host;
• adding a default route in the forwarding table pointing to a forwarder function that is configured to handle non-local traffic relative to the switch, the forward function is implemented on another network different from the overlay network, and resides on a network fabric connected to the overlay network via the switch;
• and
• updating the forwarding table only based on updates to the virtual machines hosted on the local host or addition of new virtual machines hosted on the local host.
