Abstract
In embodiments disclosed herein involve receiving a first packet, where the first packet originated from a first device on a first virtual local area network (VLAN) in a first plurality of VLANs, where routing is enabled among each of the first plurality of VLANs. A first temporary value is assigned to a first VLAN identifier associated with the first packet, where the first temporary value corresponds to the first plurality of VLANs. Additionally, the first packet is processed based on a plurality of flow tables. Further, a first destination value is assigned to the first VLAN identifier, where the first destination value corresponds to a second VLAN in the first plurality of VLANs, and the first packet is transmitted to a second device on the second VLAN.
