I think that I shall never see A graph more lovely than a tree. A tree whose crucial property Is loop-free connectivity. A tree that must be sure to span So packets can reach every LAN. Firest, the root must be selected. By ID, it is elected. Least-cost paths from root are traced. In the tree, these paths are placed. A mesh is made by folks like me, Then bridges find a spanning tree. --Radia Perlman Tom Lisa wrote: > Priscilla, > > Didn't Radia write a poem that starts something like > "I have never seen a tree as lovely as a spanning tree?" > > BTW, is it still possible to get a "free" copy of 802.1s & w. > I looked on the IEEE site but couldn't find them. > > Prof. Tom Lisa, CCAI > Community College of Southern Nevada > Cisco ATC/Regional Networking Academy > "Cunctando restituit rem" > > Priscilla Oppenheimer wrote: > > Get a copy of Cisco LAN Switching by Kennedy Clark and Kevin > Hamilton.
