Given a weighted undirected network with arbitrary node names, we present a compact routing scheme, using a(n,) space routing table at each node, and routing along paths of stretch 3, that is, at most thrice as long as the minimum cost paths. This is optimal in a very strong sense. It is known that no compact routing using o(n) space per node can route with stretch below 3. Also, it is known that any stretch below 5 requires (n,)space per node.
