Abstract
A method for efficient data forwarding in a networked device is provided. The method includes receiving a first packet from a first VLAN into a load balancer of the networked device and forwarding the first packet from the load balancer to a second VLAN internal to the networked device, wherein an identity of the first VLAN is unknown as a result of forwarding the packet from the first VLAN to the second VLAN. The method includes determining the identity of the first VLAN, based on a source IP address of the first packet and a map of IP addresses and VLANs. The method includes sending a second packet from one of a plurality of nodes, in response to the receiving, with the source IP address of the first packet as a destination IP address of the second packet and with a field of the second packet identifying the first VLAN.
