EAPS works with multiple ring networks to support more complex topologies for interconnecting multiple EAPS domains. This allows larger EAPS end-to-end networks to be built from edge to core.
Note
Minimal EAPS support is provided at all license levels. EAPS multiple ring topologies and common link topologies are supported at higher license levels as described in the Switch Engine 32.7.1 Feature License Requirements document.The simplest multiple ring topology uses a single switch to join two EAPS rings.
The common link feature uses two switches, which share a common link, to provide redundancy and link multiple EAPS rings.
