16. Rapid Spanning Tree Protocol 802 1W

CCNA BOOST
Chap 8. LAN Switch Configurations

[@marcozu533]

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.

Thank you! very well explained. I , as a beginner, can really understand it easily.

[@PkaiMeas]

OMG, I finally found this easy to understand Video on RSTP

[@RebazCh]

Thanks So Much I Understood From You ,Hope You Continue 😙

[@chidhu30888]

Greatly explained

[@ebalarampatra9303]

ohh chiruu 6 months earlier you visited this video :)

[@tsvetomilvalchev7037]

Thank you. Very helpful.

[@khalidmahmoud6591]

Very helpful

[@SnoiperTV]

usefull even for ccnp

[@Buu0105]

Thanks for sharing!

Alternate port immediately transition into forwarding, but backup port goes into diff. port states.

[@disneykidzshowhd4377]

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?

[@dgilvani]

He misspoke. He meant learning.

[@markusscott6696]

I dont understand (9.15 min) Listening state in RSPT????

[@jcornwall6228]

I hope he meant learning state

[@lucas93177]

There are a lot of mistakes in this video....

[@anjilkhadka3633]

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
