The common-link topology supports multiple EAPS domains (spatial reuse) on each ring as shown in EAPS Common Link Topology with Spatial Reuse.
Note
If you are using the older method of enabling STP instead of EAPSv2 to block the super loop in a shared-port environment, you can continue to do so. In all other scenarios, we recommend that you do not use both STP and EAPS on the same port.
