RSTP (Rapid Spanning Tree)

RSTP (802.1W) in the enhancement of (802.1D)

RSTP was crated by IEEE to get rid of the slow convergence of STP where it takes 50 seconds to bring the port up from Discarding (Blocking) to Forwarding .
RSTP convergence is in few seconds (3 Hello Timers) or withing few milliseconds of a Physical Link failure.
It does it so quickly because there is no Listening mode in RSTP. Ports can directly move from Discarding mode to Learning & Forwarding Mode.
RSTP is backwards-compatible with standard STP (you can run STP & RSTP in the same Network)
RSTP has inbuilt Cisco proprietary features like Backbone fast, Uplink fast, Portfast, BPDU Filter.
In RSTP, Not only RB but all the other Non-Root Bridges will also be sending & receiving the BPDUs to make the convergence faster.
are slightly different as compared to STP
RSTP is enabled by default on newer Cisco Switches which skips the Listening & Learning State that means is also enabled by default on RSTP running Switches on Edge ports.
Another method of preventing Loop / preventing hackers attack is using .
