This multiplicity of the locators, although the ID is single, implies multiple I-L vectors for a host and also affects DNS entries. This is equivalent to requiring IP hosts to be configured with multiple PA addresses. Have we solved the problem? Any improvement over the current IP situation? I'm afraid not. Multi-homing is not improved. -- DY
