Use the ip lisp proxy-itr command to enable IPv4 LISP Proxy Ingress Tunnel Router (PITR)
Usage Guidelines
functionality on the Cisco NX-OS device. The Cisco NX-OS device receives native packets from
non-LISP sites that are destined for LISP sites, encapsulates them, and forwards them to the ETR that is
authoritative for the destination LISP site EID.
PITR services are required to provide interworking between non-LISP sites and LISP sites. For example,
when connected to the Internet, a PITR acts as a gateway between the legacy Internet and the
LISP-enabled network. The PITR must advertise one or more highly aggregated endpoint identifier
(EID) prefixes on behalf of LISP sites into the underlying DFZ (that is the Internet) and act as an ITR
for traffic received from the public Internet.
When you enable PITR services by using the ip lisp proxy-itr command, the PITR creates
LISP-encapsulated packets when it sends a data packet to a LISP site, sends a data probe, or sends a
Map-Request message. The outer (LISP) header address family and source address are determined as
follows:
OL-25345-01
ip lisp proxy-itr ipv4-local-locator [ipv6-local-locator]
no ip lisp proxy-itr ipv4-local-locator [ipv6-local-locator]
IPv4 locator address used as a source address for encapsulation of data packets,
a data probe, or a Map-Request message.
(Optional) IPv6 locator address used as a source address for encapsulation of
data packets, a data probe, or a Map-Request message when the locator-hash
function returns a destination Routing Locator (RLOC) in the IPv6
address-family.
