Multiple EAPS Domains

This section illustrates how you can work with more than one EAPS domain.

EAPS Data VLAN Spanning Two Rings Connected by One Switch

Figure 16 shows how a data VLAN could span two rings interconnected by a common switch—a
"figure eight" topology. In this example, there is an EAPS domain with its own control VLAN running
on ring 1 and another EAPS domain with its own control VLAN running on ring 2. A data VLAN that
spans both rings will be added as a protected VLAN to both EAPS domains. In
have two instances of EAPS domains running on it: one for each ring.
