I've a ring topology where run REP with Cisco ME-34xx and works fine. However I deployment others 'non-REP' switches in this ring. After do it, a fail betwen non-REP switches, dosen't change the REP topology and keeps the Aternated port in Block state, and isolated non-REP switch. I've used "edge no-neighbor" in the edge non-REP, but as the interface that goes down isn't directly connected, REP doesn't recognize the topology change.
