Just a little summary of the video 802.1d(STP) convergence = 50s 802.1w(RSTP) convergence =< 10s 802.1w(RSTP) Timers - Max Age Timer is 6 seconds - No more Forward Delay Timers Port States - Forwarding - Learning - Discarding(Listening + Blocking + Disabled): - Will not send or receive frames - Will not learn MAC address - Will receive BPDUs Port Roles - Root - Designated - Alternate - Backup: is used when multiple ports are connected to the same network segment(hub) 802.1w & Physical Connections - Point-to-point Link: e.g. two switches are connected via a full duplex Ethernet connection - Edge Connection: e.g. a switch is connected to a PC - Share Connection: e.g. a switch is connected to a hub (Not benefit from RSTP) 802.1w convergence - Stable state -> add new link. Switch A will take a proactive approach and block the rest of the ports - Negotiate with the Root Bridge - Switch A update BPDU - Switch B and the rest switches repeat the same the process with A
Just a little summary of the video
802.1d(STP) convergence = 50s
802.1w(RSTP) convergence =< 10s
802.1w(RSTP) Timers
- Max Age Timer is 6 seconds
- No more Forward Delay Timers
Port States
- Forwarding
- Learning
- Discarding(Listening + Blocking + Disabled):
- Will not send or receive frames
- Will not learn MAC address
- Will receive BPDUs
Port Roles
- Root
- Designated
- Alternate
- Backup: is used when multiple ports are connected to the same network segment(hub)
802.1w & Physical Connections
- Point-to-point Link: e.g. two switches are connected via a full duplex Ethernet connection
- Edge Connection: e.g. a switch is connected to a PC
- Share Connection: e.g. a switch is connected to a hub (Not benefit from RSTP)
802.1w convergence
- Stable state -> add new link. Switch A will take a proactive approach and block the rest of the ports
- Negotiate with the Root Bridge
- Switch A update BPDU
- Switch B and the rest switches repeat the same the process with A
This explanation is clean, clear and concise. I recommend watching this video before you bother to read or view any other information on the topic.
i was CCNA Lammle 911 pages completed 2002 years
Thank you so much.
Foysal
OMG, I finally found this easy to understand Video on RSTP
Thank you! very well explained. I , as a beginner, can really understand it easily.
Greatly explained
ohh chiruu 6 months earlier you visited this video :)
Thank you. Very helpful.
Thanks So Much I Understood From You ,Hope You Continue 😙
Thanks for sharing!
usefull even for ccnp
Very helpful
Alternate port immediately transition into forwarding, but backup port goes into diff. port states.
I dont understand (9.15 min) Listening state in RSPT????
I hope he meant learning state
I thought he said earlier that learning state and listening state are gone in RPVST, why it's still there in the RSTP table, can someone explain?
He misspoke. He meant learning.
There are a lot of mistakes in this video....
yes when a there is a new new link connected the root bridge goes to learning state not listening coz rstp does not support listening state
