Definition and Components
LISP: Definition
LISP: Locator/Identifier Separation Protocol
IP protocol
LISP is a protocol for the transmission of IP
packets.
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 address 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 ex-
ternal header contains the RLOC.

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.

Possible Uses
•
LISP is useful if technical or organization reasons make
it preferable to keep the same IP addresses, even when
you switch Internet service providers.
Mobility example: When you change locations, devices
do not lose their identity (host devices, VM).
•
LISP is suitable for communication between IPv4 and
IPv6 networks.
•
Transport of address families: IPv4 via IPv4, IPv4 via
IPv6, IPv6 via IPv6, IPv6 via IPv4
Example: The encapsulation of IPv6 packets in IPv4
headers allows IPv6 web sites to be connected over
IPv4.
Configuring FRITZ!Box as a LISP Router
FRITZ!Box as a LISP Router
•
The FRITZ!Box can be configured as a LISP router.
•
As a LISP router the FRITZ!Box is an xTR (ETR and ITR).
Preparations
You need a LISP provider.
Register with a LISP provider.
PETR (Proxy ETR)
A PETR (Proxy ETR) is required for communica-
tion between LISP sites and non-LISP sites. On
the LISP site it works like a LISP router; on the
non-LISP site it works like a native IP router.
PITR (PROXY ITR)
A PITR (Proxy ETR) is required for communica-
tion between LISP sites and non-LISP sites. On
the LISP site it works like a LISP router; on the
non-LISP site it works like a native IP router.
xTR
xTR is what we call a component that is both
ETR and ITR. xTR is also known as a tunnel
endpoint or encapsulation endpoint.

FRITZ!Box as a Wireless Access Point
The FRITZ!Box is a wireless access point for wireless devices like note-
books, tablets or smartphones. The FRITZ!Box can establish wireless
LAN connections compliant with the fast wireless AC standard and the
wireless N standard in two frequency bands at the same time. The
FRITZ!Box is preconfigured with encryption using today’s safest meth-
od WPA2. This encryption method is supported by most of the latest
wireless devices. The FRITZ!Box supports wireless LAN convenience
functions like night service and WPS Quick Connection.

Switching the Wireless Radio Network On and Off by Schedule
You can configure a schedule for times at which the wireless
network of the FRITZ!Box is to be turned on and off automati-
cally. This reduces the power consumption of the FRITZ!Box
The FRITZ!Box schedule also affects any other AVM products
connected in the network, the FRITZ!WLAN Repeater, for in-
stance: the radio network of these devices is also switched
on and off for the specified times.
1.
Open the FRITZ!Box user interface; see
page 25
.
2.
Open the “WLAN / Schedule” menu.
3.
Enable the schedule for the wireless radio network.
4.
Configure the settings for the schedule:
–
With the options “Turn off wireless LAN daily” and
“Switch wireless LAN off according to schedule” you
define the intervals for switching.
–
You can also select the option “The radio network
cannot be switched off until no more wireless LAN
devices are active”.
5.
Click “Apply” to save your settings.
Now the schedule of the FRITZ!Box is enabled and configured.
In the Help of the FRITZ!Box user interface you can find de-
tailed instructions.
