Change of STP priority to root primary
The CORE switch is the root bridge of the network and has priority 24576. To eliminate the risk of inserting a switch in the network with a priority lower than 24576 and generating a root

Spanning Tree Priority: Root Primary and Root Secondary
To prevent having a suboptimal network, we can set the spanning tree priority using the root primary and root secondary commands.
STP, root primary and root secondary?
The second command is telling another switch I want you to be my backup root bridge, the switch will then lower its priorty number to the next increment higher than the root bridges priority number. This
Configure STP Root Bridge on Cisco Catalyst Switches
Learn how to configure the root bridge on Cisco switches using priority commands. Includes design guidance and common configuration mistakes.
Understand and Mitigate Network Loops (STP)
Configure RSTP to Prioritize Core Switches: Configure Spanning Tree Protocol settings to prioritize core switches. Setting STP priorities properly ensures that
How to change Spanning Tree Bridge Root Priority value and What is
Every Bridge (Switch) Participating in a Spanning Tree Protocol network is assigned with a numerical value called Bridge Priority (Switch Priority) Value. By default, all Cisco Switches has a Bridge
Solved: Re: STP working on core switches
Hello @yadhukrishna, if the two Nexus 9000 core switches form a vPC pair you should consider the use of the feature under vpc domain peer-switch you will need to configure the same
How to change Spanning Tree Bridge Root Priority value and What is
Bridge Priority (Switch Priority) value decides which Switch can become Root Bridge (Root Switch). You can lower the the Switch Priority value in a Spaning Tree Protocol switch, so that we can make that
How to Configure Root Bridge on Cisco Switch | GNS3
You choose the Root Bridge by lowering one switch priority by hand. You open the CLI in GNS3 and set spanning-tree vlan 1 priority 4096. This
Spanning-Tree VLAN Root Primary Command on
Command Spanning-Tree VLAN Root Primary Use This command sets the switch to become root for a given VLAN. It works by lowering the
STP Topology Tuning > Advanced STP Tuning | Cisco
Generally, root switches are at Layer 2/Layer 3 boundaries. The best way to prevent erroneous devices from taking over the STP root role is to set the
Determining the RSTP/STP Root Bridge on an MS
Best practice dictates the root bridge to be the core of the network, this can be accomplished by manually setting the priority of the switch selected to be the
Spanning Tree
All are connected directly to the core switch with no daisy chaining. Core switch is set to be the root by having its priority set to 0. All other switches
Root Bridge Placement in Spanning Tree Protocol –
For the best protection of the STP topology to not go to incorrect switches, setting the primary root priority to 0 and the secondary to 4096 will
Root Bridge for a Access level switch. Spanning Tree bottlenecks
In one of our site, i noticed that the spanning tree elected a access level switch as the root bridge. Our topology follows cisco heirarchy Core>>Distribution>>Access switch topology.
Spanning Tree Topology Tuning and Optimization
Spanning Tree Port Priority The alternate port is selected utilizing the STP port priority if there are multiple links between the switches. So when the root port fails, the switch will choose a link from the
STP Topology Tuning > Advanced STP Tuning | Cisco
The best way to prevent erroneous devices from taking over the STP root role is to set the priority to 0 for the primary root switch and to 4096 for the secondary root
Spanning Tree Priority: Root Primary and Root Secondary
you will need to configure the same STP bridge priority on both devices but from external device point of view they will see only one device acting as the root bridge ( one of the two chassis
Does changing the Spanning-tree root to preferred core SW cause
Only 2 Vlans in the LAN. Each Access switches with 2 dot1q uplinks connects to Core Switches -most comon design. It is observed that one of the access switch acting as spanning-tree
Understanding Spanning Tree Protocol (STP) & Best Practices
To make a loop-free environment, the edge switches elect the switch with the lowest priority as the new root bridge. The topology above would break into two separate instances of STP because they have
How to Configure Root Bridge on Cisco Switch | GNS3
Learn how to configure a Cisco Switch device with Root Bridge with Priority with GNS3 with our guide. Select Central Switch manually!
Spanning Tree Root Bridge Election on Cisco Switches
You can manipulate the Root Bridge Election by setting Bridge priority on your switches. The default value is 32768, and the lowest number is preferred. In the
Why is Distribution Layer switches preffered to be Root?
This means that your layer two domain ends at the distribution switches so this is the natural point to place your STP root. The distribution switches will be running a routing protocol towards the core
