RSTP convergence speed is faster than STP. Which of the following statements are correct? (Multiple Choice)
A . There is only one standard for detecting whether the topology changes in RST
B . A non-edge port migrates to the Forwarding state.
C . In STP, in order to avoid temporary loops, at least one forwarding delay must be waited. After all network port roles are determined, all ports can forward them.
D . The P/A negotiation process can continue to be passed downstream
E . Once the P/A negotiation is unsuccessful, the selection of the designated port needs to wait for two Forward delays. The negotiation process is the same as ST
