Map-Resolvers also send Negative Map-Replies directly back to an ITR in response to queries for
non-LISP addresses.
When deploying a LISP Map-Resolver, follow these guidelines:

This example shows how to configure the IPv6 LISP Map-Resolver functionality on the NX-OS device.

When a Map-Resolver is configured to use the LISP ALT for endpoint identifier to Routing Locator
(EID-to-RLOC) mapping resolution, the Map-Resolver configuration must include the ipv6 alt-vrf
command.
When a Map-Resolver is configured concurrently with a Map-Server as a stand-alone system (when
it is not connected to any ALT and it has full knowledge of the LISP mapping system for a private
LISP deployment), using the ipv6 alt-vrf command is not required.
When a Map-Resolver supports a LISP deployment that is configured for virtualization, you must
concurrently configure the Map-Resolver with a Map-Server and see registrations from all ETRs in
the LISP network to properly resolve Map-Requests when instance IDs are used. A Map-Resolver
cannot forward a Map-Request with an instance ID over the LISP ALT, as would be the case in a
nonvirtualized configuration. The Map-Resolver can only query EID-tables that are maintained by
the concurrent Map-Server for EID-to-RLOC mapping resolution in a virtualized LISP deployment.
Description
Configures which VRF that LISP should use when sending Map Requests
for an IPv4 EID-to-RLOC mapping directly over the ALT.
