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。 - ...
2. Types of Spanning Tree Protocol[1] 802.1D –This is also known as CST (Common Spanning Tree). It is a spanning tree standard developed by IEEE which elects only one root bridge per whole topology. All the traffic flows over the same path (the best path to the root bridge) but th...
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...
To communicate spanning tree concepts correctly, it is important to refer to the particular implementation or standard in context. The latest IEEE documentation on spanning tree (IEEE-802-1D-2004) says, “STP has now been superseded by the Rapid Spanning Tree Protocol (RSTP).” The IEEE uses ...
Central to the way that spanning tree protocols operate is the use of bridge protocol data units (BPDUs). When you enable spanning tree protocols on Layer 2 devices on a network, the devices send BPDUs to each other, for the purpose of learning the redundant paths and updating their L2 ...
Spanning Tree Protocol (STP) is a network protocol which runs on bridges and switches. The main purpose of STP is to prevent the bridge loop by providing redundant paths in the network as loops are deadly to a network. It also provides automatic backup paths ...
· Protocol version ID—Spanning tree protocol version ID. The protocol version ID for STP is 0x00. · BPDU type—Type of the BPDU. The value is 0x00 for a configuration BPDU. · Flags—An 8-bit field indicates the purpose of the BPDU. The...
Spanning tree was standardized in the IEEE 802.1d specification. The purpose of the spanning tree protocol (STP) is to identify and temporarily block the loops in a network segment or VLAN. The switches run the STP, which involves electing a root bridge or switch. The other switches measure ...
