Spanning Tree for Dummies - Poem From Radia Perlman


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.

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.
