FIELD: physics, computer engineering.
SUBSTANCE: invention relates to computer network engineering. The technical result is achieved through a 3-rd layer switch which is configured using an aggregated VLAN, comprising a plurality of VLAN, and searches for information relating to conformity between IP addresses and VLAN in order to determine whether a VLAN is found in the aggregated VLAN, which corresponds to a final IP address in a packet; if the VLAN which corresponds to the final IP address is found, the packet is forwarded to that VLAN only.
EFFECT: high efficiency of forwarding a packet in an aggregated virtual local area network (VLAN) script.
