Uli, what they, Jason and Khaled, have said is correct. But I will say you are correct and your co-workers are incorrect :). STP is a mechanism to prevent loops. Network design is used to provide redundancy. If that design provides redundant paths then STP is used to prevent redundant paths from creating loops.

In my understanding STP is for loop prevention and not for redundancy, right ? but why my colleague and people I met they said it's for redundancy (those guys are already in this business for at least 3 years experience).Thus, I always argue with them..hmm am I missed something here ? because for redundancy we can use HSRP, GLBP and VRRP.
