In a network of LANs connected by bridges, packets are sent from one LAN to another through intermediate bridges. Since, more than one path may exist between two LANs, packets may have to be routed through multiple bridges. Why is the spanning tree algorithm used for bridge-routing?
-
- For shortest path routing between LANs
- For avoiding loops in the routing paths
- For fault tolerance
- For minimizing collisions
- For shortest path routing between LANs
Correct Option: B
By the definition
Spanning tree protocol (STP) is a link layer network protocol that ensures a loop-free topology for any bridged LAN. Thus, the basic function of STP is to prevent bridge loops and ensuing broadcast radiation and this is why the STP is used for Bridge Routing.
