A network device may provide Layer-2 (L2) based tunneling to offload tunneling performed by tunneling gateways. The network device may selectively offload tunneling handled by a tunneling gateway by determining whether addressing or locality information of a destination network device for a traffic packet is available. When the locality information of the destination network device for the traffic packet is available, the network device may establish a separate tunnel for communicating the traffic packet to the destination network device instead of forwarding the traffic packet to the tunneling gateway. The separate tunnel may be configured to bypass the tunneling gateway. When the addressing or locality information of the destination network device for the traffic packet is not available, the network device may forward the traffic packet to the tunneling gateway for tunneling of the traffic packet by the tunneling gateway.
