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 or nonedge ports, TCNs are generated
and flooded.
C.
When a port transitions to the forwarding state on nonedge ports, the local switch generates
and floods TCNs.
D.
Switches do not flush MAC addresses learned through the same port through which TCNs
arereceived.
E.
When a port transitions to the forwarding state on edge ports, the local switch generates and
floods TCNs.
