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 (
Figure 21 ).
Figure 21: Multiple EAPS domains per ring
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.
You can also use spatial reuse with EAPS shared ports as shown in Figure 22 . The advantage of this
topology is that you can configure common links between multiple rings and configure multiple EAPS
domains on each ring. To utilize this topology and configure EAPS shared ports, you must have a core
or an advanced core license.
