MSTP is compatible with RSTP and STP, and RSTP is compatible with STP. Table 1-1 compares the three spanning tree protocols. Table 1-1 Comparison among STP, RSTP, and MSTP Spanning Tree Protocol Characteristics Application Scenario STP Builds a loop-free tree topology to prevent broadcast ...
Spanning Tree Protocol (STP) is a widely used and effective method for preventing loops in a network. It helps prevent loops by actively monitoring thenetwork topologyand selectively blocking redundant links. This ensures that there is only one active path between any two network devices. By doing...
Spanning Tree Protocol (STP) 的主要目的是**在数据链路层(Layer 2)消除网络中的环路,保持网络拓扑的无环状态**。具体分析选项如下: - **A.防止路由环路**:路由环路发生在网络层(Layer 3),而STP作用于数据链路层,此选项错误。 - **B.创建默认路由**:默认路由是路由器(Layer 3)的功能,与STP无关。 - ...
解析:Explanation:STP’s main task is to stop network loops from occurring on your Layer 2 network (bridges or switches). It vigilantly monitors the network to find all links, making sure that no loops occur by shutting down any redundant ones. STP uses the spanning-tree algorithm (STA) to...
Spanning Tree Protocol (STP) is a Layer 2 protocol that aids in preventing loops in Ethernet networks, such as a local area network.
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 ...
Spanning Tree Protocol; Token Ring; and Unidirectional Link Detection. Other Layer Two Tunneling Protocol features Additional frequently asked L2TP-related questions include the following. What is L2TP passthrough? L2TP passthrough is an L2 tunneling protocol used for point-to-point sessions via the int...
To prevent loops from causing broadcast storms and making the MAC address table unstable, the Spanning Tree Protocol (STP) runs switches when redundant links are used on the network. STP is a basic feature of datacom products including switches, routers, and WLAN products. This chapter describes...
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 ...
