Multiple Eaps Domains Per Ring-Spatial Reuse; Multiple Eaps Rings Sharing A Common Link - Extreme Networks ExtremeWare XOS Guide Manual

Multiple EAPS Domains per Ring—Spatial Reuse
To take advantage of the spatial reuse technology and broaden the use of the ring's bandwidth, EAPS
supports multiple EAPS domains running on the ring at the same time

So, a single ring might have two EAPS domains running on it. Each EAPS domain would have a
different EAPS master node. Each EAPS domain will protect its own set of protected VLANS.
In a spatial reuse configuration, do not add the same protected VLAN to both EAPS domains.

Multiple EAPS Rings Sharing a Common Link

When you configure EAPS on multiple rings with a common link, you may experience a loop situation
across both rings. To solve this problem you can configure EAPS shared ports.
NOTE
You must have a core or advanced core license to use the EAPS shared port feature.
In the example shown in
down, users on Ring 1 would not be able to communicate with users on Ring 2. To make the network
more resilient, you can add another switch, S10. The link connecting S5 to S10 is knows as the common
link, as shown in Figure 18.
