Re: RSTP and STP

Hello Dave,

basically, RSTP is an enhancement to STP, the main difference being the improved convergence when recalculating the spanning tree. RSTP convergers in roughly 1 second, whereas STP can take up to 50 seconds. Watch out though: not all switches support RSTP, and for some, you need the enhanced image to support it (e.g. the 2950 switches).

Have a look at this document as well:

Understanding Rapid Spanning Tree Protocol (802.1w)

Re: RSTP and STP

The nice thing between RSTP and STP is they are compatible... so if you have a switch A running RSTP connected to Switch B running STP, Swtich A will notice that Switch B is not a RSTP switch and it will go through the 50 seconds convergence time with switch B.
