SYSTEMS AND METHODS FOR OPTIMIZING LAYER THREE ROUTING IN AN INFORMATION HANDLING SYSTEM

摘要

An information handling system is provided. The information handling system includes systems and methods for providing an anycast MAC addressing of a virtual redundancy router protocol instance that spans a plurality of aggregation switches. The anycast MAC address may be provided by a virtual bridging device and then used as an address of a virtual IP instance accessible through the virtual bridging device. Using the anycast MAC address with the virtual IP instance, a packet to be routed from one rack to another rack in a data center may be dynamically routed based a current load distribution.

1. An apparatus comprising:
an aggregation switch coupled to a plurality of top-of-rack switches; wherein the aggregation switch is configured to:
receive an address resolution protocol (ARP) packet from a first one of the top-of-rack switches;transmit an ARP reply to the first top-of-rack switch on behalf of a virtual bridging device being provided by the aggregation switch and one or more other aggregation switches, the ARP reply including an anycast MAC address for the virtual bridging device;receive a data packet from the first top-of-rack switch, the data packet including the anycast MAC address as a destination MAC address; andforward the data packet on behalf of the virtual bridging device.
