AIA ENHANCEMENTS TO SUPPORT L2 CONNECTED NETWORKS

摘要

A method for determining a routing for packets aggregated from multiple Layer 2 (L2) networks is provided. An ingress packet is received from an ingress inline network port and is processed to extract a source Media Access Control (MAC) address and a port identifier associated with the source MAC address. The extracted source MAC address of the ingress packet is looked up in a MAC address table. The ingress packet is forwarded to an inline tool device. When an egress packet is received back from the inline tool device it is processed to extract source and destination MAC addresses. The extracted source and destination MAC addresses of the egress packet are looked up in the MAC address table. The egress packet is transmitted to an egress inline port based on the looked up destination MAC address.

1. A method for determining a routing for packets aggregated from multiple Layer 2 (L2) networks, the method comprising:
processing an ingress packet received from an ingress inline network port to extract a source Media Access Control (MAC) address and a port identifier associated with the source MAC address; looking up the extracted source MAC address of the ingress packet in a MAC address table; forwarding the ingress packet to one or more inline tool devices; processing an egress packet received from the one or more inline tool devices to extract source and destination MAC addresses; looking up the extracted source and destination MAC addresses of the egress packet in the MAC address table; and transmitting the egress packet to an egress inline port based on the looked up destination MAC address.
