Definition and Components
LISP: Definition
LISP: Locator/Identifier Separation Protocol
IP protocol LISP is a protocol for the transmission of IP pack-
ets.
IP address pair LISP uses IP address pairs:
• One IP address for identification, which is
called the EID (Endpoint Identifier). The EID
can be the IP address of a host or an entire IP
subnet.
• One IP address for the location, known as the
RLOC (Routing Locator). The RLOC is the IP ad-
dress of the LISP router.
Tunnel protocol LISP is a tunnel protocol.
A LISP packet consists of an internal IP packet
and an additional external header. The header of
the internal packet contains the EID; the external
header contains the RLOC.
