The common-link topology supports multiple EAPS (Extreme Automatic Protection Switching) domains (spatial reuse) on each ring as shown in the following figure.
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 recommendsthat you do not use both STP and EAPS on the same port.
