LISP: FRITZ!Box as a LISP Router
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 is the FRITZ!Box is an xTR (ETR and ITR).
Preparations
You need a LISP provider.
Register with a LISP provider.
All of the information you need to configure the FRITZ!Box as a
LISP router is supplied by the LISP provider.
PETR (Proxy ETR) A PETR (Proxy ETR) is required for communication
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 communication
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.
