WebSome edge switch could randomly own the lowest MAC address in your network and root the spanning tree. Not only would any reboot or other offline case topple over the tree but the data flows would also align along that randomly rooted tree - chances are that your core switches don't talk to each other directly but through some lower-tier switch. WebThe STP Algorithm. The Spanning-Tree algorithm performs a couple of steps to make sure that the topology is loop-free and Ethernet is going to work correctly: Electing a Root Bridge - The very first thing that STP does is to elect a Root Bridge. This is the most important switch in the topology. It will be the root of the loop-free tree.
