Abstract: Systems and methods for a VLAN switching and routing service (VSRS) are disclosed herein. A method can include generating a table for an instance of a VSRS, which VSRS couples a first virtual layer 2 network (VLAN) with a second network. The table can contain information identifying IP addresses, MAC addresses, and virtual interface identifiers for instances within the virtual layer 2 network. The method can include receiving with the VSRS a packet from a first instance designated for delivery to a second instance within the virtual layer 2 network, identifying with the VSRS the second instance within the virtual layer 2 network for delivery of the packet based on information received with the packet and information contained within the table, and delivering the packet to the identified second instance.
