User is allowed to set path cost as 0 but it does participate in port role selection. > Port role is dependent on path cost; port with lesser path cost becomes root. > In the current issue, though port has a lesser value of path cost (0), it is not becoming root.
Interface with path-cost as 0 does not become root or it does not restrict user to set path cost value as 0.
STP is enabled on F5OS enabled platforms and > Path cost of any of the interface is set to some number > One of the interface has default value or value 0.
Don not keep path-cost value as 0.
> Default value of path-cost is modified to 1. > Range of the path-cost is updated, it starts from 1 instead of 0.
