We will also enable a newer version of the Spanning Tree which is a Rapid Spanning Tree. Packet Tracer CCNA Practical Labs Cisco Packet Tracer CCNA. It support most routing, switching, wireless, and basic firewall devices with latest IOS.

Root Bridge is selected as per the VLAN number so we have to mention that for which VLAN, the switch is a root. Cisco Packet tracer is a network simulator software for CCNA exams preparation. In this lab, we will try changing the priority of a switch to be able to select the switch of our choice as a Root Bridge. We cannot, however, change the MAC address of a switch so we will have to change the priority number of switches to influence the selection of a Root Bridge. Therefore, for maximum optimization, it is very important to select the right switch as a Root Bridge. Hence, every Spanning Tree Network must have the best Switch as a root.īy default, the Spanning Tree is enabled on the switches so if we create a redundant connection on switches then the Spanning Tree Protocol will automatically come into action to prevent a loop in the network. And if that switch is slow then it will slow down the entire network because its network traffic will pass through that switch. But the problem is that by default any switch which has the lowest Bridge ID can be automatically selected as a Root Bridge. CCNP ENARSI v8 Labs & Packet Tracer (Answers Version) Packet Tracer - CCNP ENARSI v8: 1.2.1 Packet Tracer - DHCP for IPv4 and Routing Between VLANs: 2.2.1 Packet Tracer - Configure Basic EIGRP with IPv4: 4.2.1 Packet Tracer - Troubleshoot EIGRP for IPv4: 5.2. And by default, all switches have the same priority number – 32768 to be precise – so the Spanning Tree relies on a MAC address for the selection of Root Bridge. Bridge ID is made up of a priority number and the MAC Address. So, whichever switch will have the lowest Bridge ID, that very switch will be selected as a Root Bridge. The root is selected on the basis of a Bridge ID. Therefore, it is very important to choose the best switch in the network as a Root Bridge. And all the other switches choose the best way to reach a Root Bridge and block the redundant links. Root Bridge is the most important switch in a Spanning Tree Network. And to prevent those loops in networks the Spanning Tree Protocol chooses the best link while blocking the redundant links. However, redundant connections create a loop in the network. Redundant connections play a very crucial role as it eliminates the single point of failure in the network. In typical network topology, we have redundant connections between switches.
