Forwarding Port in Layer 2 STP topology

Answer Posted / guest

@ Jitendera Sinh- Please don't misguide if u don't know the answer.

BPDU's are packets exchanged b/w switches to to know the interface to which it is connected to. (not protocol.

TO answer the question you need to explain the STP.
This is how entire STP works in simple words.

1.Lowest Bride ID will be elected as ROOT bridge.
2.All the ports of ROOT bridge will be DP
3.All ports directly connected to ROOT bridge will become RP
4.Based on the path cost to reach ROOT bridge, the Port will become RP(Other than directly connected bridge)
5.The Port to which RP is connected will be a DP.
6.All other(Extra) port will be either DP/BP based on the Bridge ID.(Lower will be DP)
