What is a disadvantage of the spanning tree algorithm?

Disadvantages: There are automatic recalculations in spanning trees whenever a new spanning tree is formed, or any new network spanning tree is formed, but the drawback of this is it may cause a network outage sometimes when it modifies automatically.

Why is STP not good?

The most serious shortcoming is that STP has a brittle failure mode that can bring down entire data center or campus networks when something goes wrong. Though modifications and enhancements have addressed some of these risks, this has happened at the cost of technical debt in design and maintenance.

What is a spanning tree issue?

As the name suggests, spanning tree resolves loops in your network by creating a logical tree structure between the switches. One switch becomes the root of the tree, and is called the root bridge. The problem is that, by default, every switch has the same priority value (32768).

What is spanning tree algorithm in networking?

The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. In 2001, the IEEE introduced Rapid Spanning Tree Protocol (RSTP) as 802.1w.

What is spanning tree with example?

A minimum spanning tree is a special kind of tree that minimizes the lengths (or “weights”) of the edges of the tree. An example is a cable company wanting to lay line to multiple neighborhoods; by minimizing the amount of cable laid, the cable company will save money. A tree has one path joins any two vertices.

Can STP and RSTP be mixed?

It is possible to mix PVST and MST (RSTP requires MST), but it needs some planning, and it can be fragile, as you have discovered. You would probably be better off using the same STP version across all your switches. You could change the STP on the Cisco switches to match the rest of the switches.

Should I enable STP?

Broadcast storms caused by loops can slow or stop traffic on your network, but STP can prevent loops by ensuring that only one path between each set of switches is active. You must enable or disable STP or RSTP for each network location in which you are using Insight Managed Switches.

What are two drawbacks to turning spanning tree off and having multiple paths through the Layer 2 switch network choose two?

What are two drawbacks to turning spanning tree off and having multiple paths through the Layer 2 switch network? (Choose two.) The switch acts like a hub. Port security becomes unstable. The MAC address table becomes unstable.

Which loops are avoided with STP?

The Spanning Tree Protocol (STP) is a network protocol that is used to eliminate bridge loops in Ethernet LANs. STP prevents network loops and associated network outage by blocking redundant links or paths.

What is the difference between a tree and a spanning tree?

Difference between a tree and spanning tree?! A tree is a graph that is connected and contains no circuits. A spanning tree of a graph G is a tree that contains every node of G.
