l#states
Learning and Forwarding
STP States (old) RSTP States
Disabled Discarding
Blocking Discarding
Listening Discarding
Learning Learning
Forwarding Forwarding
RSTP = Discard – Learn – Forward
In convergence there is no more learning. SO “A. Discard” and “D.Forward”

Just to recap:
STP = Block – listen – Learn – Forward – Disabled (not sure why it is included)
