Spanning trees connect all the nodes of a graph with the minimum number of edges without introducing any loops or cycles. Any graph can have many spanning trees. For a graph of n nodes, a spanning tree will always have exactly n - 1 edges. Read What is a Spanning Tree? - Properties ...
what is a loop? a loop is a programming construct that allows you to repeat a set of instructions multiple times. it's like telling the computer, "hey, do this thing over and over until a certain condition is met. how does a loop work? when you use a loop, you provide an initial...
When a spanning tree protocol is deployed on devices on a network, the devices exchange Bridge Protocol Data Units (BPDUs) to calculate a loop-free network topology. The devices continuously update and exchange BPDUs to determine the ports to be blocked and those to become root ports. Port ...
To create a default route C. To provide multiple gateways for hosts D. To maintain a loop-free Layer 2 network topologyE.To E. nhance the F. unctions of SNMP 相关知识点: 试题来源: 解析 D 正确答案:D 解析:Explanation:STP’s main task is to stop network loops from occurring on your...
This is where STP comes in. STP-capable devices exchange information with one another to discover loops on the network, and then block some redundant links to trim the ring network into a loop-free tree network. This prevents packets from being infinitely replicated or propagated on the network...
What is the result of entering the command spanning-tree loopguard default?() A. The command enables both loop guard and root guard. B. The command changes the status of loop guard from the default of disabled to enabl...
What Is STP Loop Protection? In a network governed by a spanning tree protocol, a switching device maintains the status of the root port and the blocked port by continuously receiving Bridge Protocol Data Units (BPDUs) from the upstream switching device. However, if ports fail to receive BPDU...
Spanning Tree Protocol (STP) is a Layer 2 protocol that aids in preventing loops in Ethernet networks, such as a local area network.
What is Spanning Tree Protocol In a networking infrastructure, a loop occurs when network packets continuously circulate among two or more network devices without reaching their intended destination. This situation arises due to redundant or multiple paths between network devices, causing packets to trave...
Spanning Tree Protocol (STP) is used to create loop-free topology among the switches in each Layer 2 domain. A per-VLAN STP instance can be used, which enables different Layer 2 topologies. A multi-instance STP can also be used to reduce STP overhead if the topology is the same among ...
