Abstract
A spanning tree enabled n-node VLT system includes the STP running on VLT node devices that include a first VLT node device coupled to a networking device by a LAG and designated as a root bridge via the STP. A second VLT node device coupled to the networking device is part of the LAG. ICLs couple the second VLT node device to the first VLT node device. An enhanced STP engine running on the each of the VLT node devices determines that the STP has designated a first port providing one of the ICLs as a first root port, and a second port providing one of the ICLs as an alternate port. In response, the enhanced STP engine redesignates the second port as a second root port.
