Facing issue in STP

[Ritin Singh]

Hi All,

What will happen if the cable breaks between the switches Root-bridge and Non Root-bridge ?

Thanks!!

Hello @Ritin Singh,

If the cable breaks between the Root Bridge and Non-Root Bridge switches in a spanning tree network, the spanning tree algorithm will detect the link failure and initiate the process of reconverging the network.

The specific behavior during a link failure in a STP network depends on the version of the spanning tree protocol being used (STP, RSTP, MSTP,...).

Hello @Ritin Singh ,

if you are using a traditional STP network, if a link fails, it can take up to 50 seconds for the STP algorithm to converge and re-route traffic. With RSTP, this time is reduced to less than 10 seconds. RSTP accomplishes this by using a more efficient algorithm, and by defining new port states that allow for faster recovery.

Thanks!!

Break or flapping? 

[Joseph W. Doherty]

STP "does its thing" as it does for any cable break within the STP topology.

Could you be more specific/descriptive in the "issue" you're "facing" within STP?
