+In addition, for multi-host, you will want to `make install-flannel` after `make sync-external-ip` when worker pods are up. The sync command adds an annotation `flannel.alpha.coreos.com/public-ip-overwrite` for flannel to direct the nodes to use the physical node host IP. If the flannel pod has already been created for a node, it would need to be restarted to recheck the annotation. The easiest approach is to install flannel after the annotations have been applied.
