+Všechny sw musí mít stejné:
+  * region-name
+  * revision-level
+  * VLAN to instance mapping
+Postup konfigurace:
+  - enable STP
+  - nastavit MSTP region na všech switchích
+  - nastavit root a secondary root pro všechny instance
+  - nastavit edge (access) a non-edge (uplinky) porty
+  - aplikovat BPDU protection, root guard a loop protection
