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
