I'm seeing mutiple root bridges for each vlan across our network. We have multiple switch stacks which connect to our two core switches. We are also runing vtp across the LAN so each switch has 25 vlans in it vlan database.
On the trunk ports which connect from the core switches to the switch stacks we only allow the required vlan for the switch stack. Because we restrict the vlans on the trunk ports does this mean each switch stack will need a root bridge for the vlans which are not allowed across the trunk ports which connect to the cores. Also would it be best practice to disable VTP?
