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...
What Does Spanning Tree Protocol (STP) Do? TheSpanning Tree Protocol (STP)avoids the formation of loops orbroadcast storms. It does so by blocking ports where it senses loop formation. In other words, the STP looks after the network to make it loop-free by tracking all the links and stop...
Spanning Tree Protocol (STP) is a networking protocol with a particularly long history. Back in 1995 STP was designed specifically to prevent Layer 2 network loops or broadcast storms from disrupting networks. This protocol sits on Layer 2 of the OSI model and acts as a link management protocol...
In a broad sense, STP refers to the STP protocol defined in IEEE 802.1D, Rapid Spanning Tree Protocol (RSTP) defined in IEEE 802.1w, and Multiple Spanning Tree Protocol (MSTP) defined in IEEE 802.1s. To elaborate, STP, RSTP, and MSTP provide the following capabilities: ...
As the scale of LANs continues to grow, STP has become an increasingly important LAN protocol. Root Bridge, Root Port, and Designated Port Three elements are involved in trimming a ring network into a tree network: root bridge, root port, and designated port. Root bridge: There is only one...
spanning-tree mode<protocol mode> For example, to enable Rapid STP (RSTP) on a switch, the administrator would run the following command: spanning-tree mode rstp In addition to enabling STP, an administrator must select a root bridge to serve as the network's central STP reference point. Th...
The Spanning Tree Protocol (STP) on AP wired interfaces takes effect only when a loop exists among the AP and wired devices. As shown in Figure 10-5, a single loop exists among the AC, SwitchA, SwitchB, and AP. STP can be configured on the AP's wired interfaces to break the loop...
Spanning tree protocol (STP) identifies links in the network and shuts down redundant links, preventing possible network loops and broadcast radiation on a bridged network. STP also provides redundant links for automatic failover when an active link fails. STP is enabled by default ...
Zone Routing Protocol in Computer Networking (ZRP) Abstract Routing protocols for mobile ad-hoc networks have to face the challenge of frequently changing topology‚ low transmission power and asymmetric links. Both proactive and reactive routing protocols prove to be inefficient under these ...
STP is used to prevent loops in a LAN. As a LAN expands, STP has become an important protocol for the LAN. The devices running STP discover loops on the network by exchanging information with one another, and block certain interfaces to cut off loops. Figure 8-135 Networking diagram for ...
