An EID address is not an Identifier and an RLOC
It is an identifier. It is used by the TCP and UDP socket layer. Just
because an EID is also a scoped locator inside of a site, does not
preclude it from being an identifier.
address is not a Locator. Both kinds of address
are like any IP address - they play the roles of
both Identifier and Locator. ITRs use a different
algorithm for EID destination addresses. All
other routers and all hosts make no distinction
between EID and RLOC addresses.
LISP does separate ID and locator because you can keep an EID fixed
with a system, maintaining session continuity, while changing the
locator associated with the EID.
