Indeed.

You don't configure nodes with locators (for all the very good reasons you

By taking ILNP as an example, locators are subnet identifiers, a host is
associated with multiple locators at multi-homing. 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.
