Algorhyme
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 packet can reach every LAN.
First, 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.
