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.

xTR is what we call a component that is both
ETR and ITR. xTR is also known as a tunnel
endpoint or encapsulation endpoint.
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.
