Aggregated networking device policy based routing system

An Information Handling System (IHS), comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a Policy Based Routing (PBR) engine that is configured to:
• provide a first Policy Based Routing (PBR) entry in a PBR table that redirects packets that are initially provided for forwarding via a first port that provides a first link to a first core networking device such that those packets are forwarded via a second port that provides a second link that is included in a first Link Aggregation Group (LAG) to a second core networking device;
• detect that the second port is unavailable;
• and
• provide, in response to detecting that the second port is unavailable, a second PBR entry in the PBR table that redirects the packets that are initially provided for forwarding via the first port that provides the first link to the first core networking device such that those packets are forwarded via an Inter-Chassis Link (ICL) to an aggregated networking device for transmission via the first LAG to the second core networking device.

A method for providing Policy Based Routing (PBR) for an aggregated networking device, comprising:

• providing, by a first aggregated networking device, a first Policy Based Routing (PBR) entry in a PBR table in the first aggregated networking device that redirects packets that are initially provided for forwarding via a first port on the first aggregated networking device that provides a first link to a first core networking device such that those packets are forwarded via a second port on the first aggregated networking device that provides a second link that is included in a first Link Aggregation Group (LAG) to a second core networking device;
• detecting, by the first aggregated networking device, that the second port is unavailable;
• and
• providing, by the first aggregated networking device in response to detecting that the second port is unavailable, a second PBR entry in the PBR table in the first aggregated networking device that redirects the packets that are initially provided for forwarding via the first port that provides the first link to the first core networking device such that those packets are forwarded via an Inter-Chassis Link (ICL) to a second aggregated networking device for transmission via the first LAG to the second core networking device.
