You recently implemented a Layer 2 network using RSTP. Which three statements are true regarding a topology change reconvergence scenario? (Choose three.)
A.
Switches do not flush MAC addresses learned from edge ports.
B.
When a port transitions to the discarding state on edge ornonedge ports, TCNs are generated and flooded.
C.
When a port transitions to the forwarding state onnonedge ports, the local switch generates and floods TCNs.
D.
Switches do not flush MAC addresses learned through the same port through which TCNs are received.
E.
When a port transitions to the forwarding state on edge ports, the local switch generates and floods TCNs.
