Current data center deployments, particularly layer 2 (L2) deployments that use multi-chassis link aggregation group (MC-LAG) implementations, have limitations. Such deployments use a link, known as an inter-node link (INL) / inter-chassis link (ICL), to connect peer information handling system nodes.

For a leaf node, a sub-LAG (link aggregation group) may be created to reach single-homed / orphaned nodes connected to the leaf node.
