Abstract
In one embodiment, a layer-2 network that includes a cloud switch is partitioned into a plurality of segments, each segment including one or more cloud switch domains that are coupled via a logical port to a corresponding one of a plurality of internal logical shared media links. One of the internal logical shared media links is provisioned as a hub. One or more remaining internal logical shared media links are defaulted to be spokes. A spanning tree protocol (STP) is executed within each segment. The logical port of each cloud switch domain advertises a pseudo root bridge identifier (ID) to cause the internal logical shared media link to appear attached to a Root. The advertised pseudo root bridge ID of the hub is chosen to have a higher priority than the pseudo root bridge ID of the spokes to establish a hub and spoke relationship among the segments.
