Every Bridge (Switch) Participating in aSpanning Tree Protocolnetwork is assigned with a numerical value called Bridge Priority (Switch Priority) Value. Bridge Priority (Switch Priority) Value is a 16-bit binary number. By default, all Cisco Switches has a Bridge Priority (Sw...
In any spanning tree of n nodes there will always be n - 1 edges. For a tree to be a spanning tree, it must connect all the nodes, but not form any loops or cycles. Lesson Summary Register to view this lesson Are you a student or a teacher? I am a student I am a teacher ...
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...
RSTP, an enhancement to STP, allows for rapid network topology convergence. However, both RSTP and STP have a defect, that is, all the VLANs on the same LAN share the same spanning tree. As a result, redundant links cannot be blocked byVLAN, and packets of all VLANs are forwarded alon...
VLANs are used to segment a LAN into multiple collision domains, but the STP process alone does not do this.E. Routers are used to prevent routing loops at layer 3 of the OSI model. STP operates at layer 2.反馈 收藏
During the root port selection process, a tie can occur when two or more ports on a non-root bridge have the same cost to reach the root bridge. In such cases, the following tie-breaking mechanisms are used. The Bridge ID of the forwarding switch is compared, and the switch with the ...
当输入命令'spanning - tree loopguard default'时，其作用是将环回保护（loop guard）的状态从默认的禁用（disabled）更改为启用（enabled），所以B选项正确。
What is the reason for running spanning-tree in a Cisco Single-Site Secure Network Foundation Solution?() A. To protect the network in case someone inadvertently creates a physical loop in it B. To ensure that if a ...
In a network that contains redundant paths, bridges need to continually understand thetopology of the networkto control the flow of traffic and prevent looping. To do this, they exchange bridge protocol data units (BPDUs) via an extended LAN that uses a spanning tree protocol. BPDUs are data...
