Root port vs. Designated Ports
I'm sorry if this is a totally beginners question. At one point I thought I had a full understanding of STP, but then I started thinking a bit deeper and realized I had no understanding of the differences between root ports and designated ports.
This is what I understand:
- The election process for the root bridge, root port, and designated ports
- I understand that BPDUs are sent on all ports, no matter what port state
My question is basically, are designated ports only ports that will forward traffic that is received from a switch below them? And if a switch has fa0/1 as the root port, and fa0/2 as the designated port, it will only forward traffic out of fa0/1, even if a host it's trying to reach is directly connected to a switch on it's designated port?
