🌲A complete graph is fully meshed, with every pair of vertices connected by a line.
🔗A spanning tree is a minimally connected graph without loops, formed from a complete graph.
🌐Spanning tree protocol (STP) is a layer 2 protocol that prevents loops in network topology.
🏢STP selects a root bridge, determines path costs, and blocks redundant links to eliminate loops.
💡STP provides fault tolerance by activating blocked links if active links fail.
What is the difference between a complete graph and a spanning tree?
—A complete graph is fully meshed, with every pair of vertices connected, while a spanning tree is a minimally connected graph without loops, formed from a complete graph.
What is the main purpose of spanning tree protocol (STP)?
—The main purpose of STP is to prevent loops in network topology, ensuring efficient and fault-tolerant data transmission.
How does STP select a root bridge?
—STP selects a root bridge based on the lowest bridge ID among the switches in the network.
What are path costs in STP?
—Path costs in STP are calculated based on link bandwidth, with higher bandwidth resulting in lower costs. Path costs help determine the shortest path to the root bridge.
How does STP eliminate loops?
—STP eliminates loops by blocking redundant links that could cause loops, while maintaining link redundancy for fault tolerance.
