I have a question regarding a topology of 3 switches :
1. When i configure cisco switch 3750 IOS(12.2) to work with MSTP instance 0 , is it mean that i work RSTP ? or MSTP ?
2.Why i needed to define portfast for fast convergence to the Host ports for Instance 0 (otherwise convegence time was 30 sec)
but when i configured the switch instance 1 i did not have to do so.
The convegence time was less than 1 sec ?
