Properties of RLOC and EID
Components of a LISP System
RLOC
•
specifies the location where the addressed network
(network segment or network device) is located
•
is assigned by the Internet service provider
•
is a public IP address
•
is contained in the external header of the LISP packet
•
can be an IPv4 address
•
can be an IPv6 address
EID
•
identifies a network (network segment or network de-
vice)
•
is assigned by the LISP provider
•
is contained in the internal header of the LISP packet
•
can be an IPv4 address
•
can be an IPv6 address
•
can be a public IP address
•
can be a private, non-public IP address
Mapping system
The mapping system is responsible for allo-
cating the EIDs to the RLOCs.
ETR (Egress Tunnel
Router)
The ETR accepts IP packets whose destination
IP address contained in the external header is
the ETR’s own RLOC. ETR unpacks the LISP
packets.
ITR (Ingress Tunnel
Router)
The ITR accepts IP packets from members of
the local IP network (EID network) and packs
them into LISP packets. The external header of
the LISP packet contains the RLOC of the des-
tination network (remote EID network) as the
destination address.
