ipv6 lisp itr send-data-probe

To configure an ingress tunnel router (ITR) or Proxy ITR (PITR) to find an IPv4 endpoint identifier to
Routing Locator (EID-to-RLOC) mapping for a packet it needs to encapsulate by sending a data probe
rather than by sending a Map-Request message, use the ipv6 lisp itr send-data-probe command. To
remove this functionality, use the no form of this command.
This command has no arguments or keywords.

When a Locator/ID Separation Protocol (LISP) ITR or PITR gets a map-cache miss and needs to resolve
Usage Guidelines
an IPv4 EID-to-RLOC mapping for a destination EID, you can send a Map-Request message either in a
LISP Encapsulate Control Message (ECM) to the Map Resolver configured by using the ip lisp itr
map-resolver command, or directly over the Locator/ID Separation Protocol Alternative Topology
(LISP-ALT) by using the ip lisp alt-vrf command. In either case, the first packet of the flow that caused
the map-cache miss is dropped. Once the Map-Reply populates the map cache, subsequent packets to the
same destination are forwarded directly by LISP.
When you configure an ITR or PITR by using the ip lisp itr send-data-probe command, you must also
Note
configure the ITR or PITR to use the LISP-ALT by using the ip lisp alt-vrf command because the
data-probe is sent over the LISP-ALT.
We do not recommend that you use the LISP data probe because this mechanism forwards data plane
Caution
traffic over the LISP-ALT. The LISP-ALT is intended to function solely as a control plane mechanism
for LISP and its use subjects it to denial of service attacks.
