Поэзия 2
Оказывается, что к стишку о STP было придумано продолжение. Посвящено оно RBridge'ам:

			   Algorhyme v2		
	
		I hope that we shall one day see
		  A graph more lovely than a tree.
		A graph to boost efficiency
		  While still configuration-free.
		A network where RBridges can
		  Route packets to their target LAN.
		The paths they find, to our elation,
		  Are least cost paths to destination.
		With packet hop counts we now see,
		  The network need not be loop-free.
		RBridges work transparently.
		  Without a common spanning tree.
