I'm unclear of the difference between the Designated Ports and Root Ports?
I know Root Ports are the ones with lowest cost to get to the Root Bridge. So, what does the Designated Port do? I'm very unclear about this.
on the opposite site of Root port u will have DP, designated port. Root switch will have all its ports as DP.
so, DP are ports downstream whereas Root ports are upstream.
thanks for the reply. I'm still confused. DPs are always forwarding BPDUs, what does RP do?
if a switch has multiple paths to the Root Bridge, after RP is selected, how will it select the DP?
