When you configure a switch to function as an IPv4 PITR, you can also configure it to use the LISP ALT
for IPv4 EID-to-RLOC mapping resolution. When configured to use the LISP ALT, the PITR sends its
map request messages directly over the LISP ALT using the virtual routing and forwarding (VRF)
referred to by the ip lisp alt-vrf command. A PITR can send a Map-Request to a configured
Map-Resolver for EID-to-RLOC mapping resolution as an alternative to sending a Map-Request directly
over the LISP ALT. (See the ipv4 map-resolver command). When using a PITR in a virtualized LISP
deployment, you must configure the PITR to use a Map-Resolver for EID-to-RLOC mapping resolution
and not the LISP ALT because the LISP ALT does not support virtualization.
A switch that is configured as an ITR performs a check to see if the source of any packet intended for
Note
LISP encapsulation is within the address range of a local EID prefix, whereas a Cisco NX-OS device
configured as a PITR does not perform this check. Unlike the Cisco IOS LISP implementation, in Cisco
NX-OS you can configure a Cisco NX-OS device to support both ITR and PITR functionality at the same
time. If you configure a Cisco NX-OS device as an ITR and as a PITR, preference goes to PITR
functionality for packet processing.
This command does not require a license.
This example shows how to configure the LISP PITR functionality on the Cisco NX-OS device, and how

When the locator-hash function returns a destination RLOC within the IPv4 address family, the
address ipv4-local-locator is used as the source address from the locator namespace.
When the locator-hash function returns a destination RLOC within the IPv6 address family
(assuming the optional address ipv6-local-locator is entered), it will used as a source locator for
encapsulation.
Description
Configures which VRF that LISP should use when sending Map Requests
for an IPv4 EID-to-RLOC mapping directly over the ALT.
Configures the Cisco NX-OS device to act as an IPv4 LISP Ingress Tunnel
Router (ITR).
