Hi all

So none of my edge switches become root, is it good practice to change the priority on them to 61440 ?

It's far more important to make sure the STP root and STP secondary are lower than 32768 which you can do manually or with the macro "spanning-tree vlan .

You can make edge switches greater than 32768 but if you are going to go to that trouble it is much easier to simply configure the above.

Hello,

          To configure a VLAN instance to become the root bridge, enter the spanning-tree vlan vlan_ID root command to modify the bridge priority from the default value (32768) to a significantly lower value.

Router# configure terminal

Router(config)# spanning-tree vlan vlan_ID root primary

Router(config)# end

If you configure as a root primary, then none of your edge switch become root.
