ipv6 lisp alt-vrf

To configure the virtual routing and forwarding (VRF) instance that the Cisco NX-OS device uses when
sending map requests for an IPv6 end point identifier (EID) to Routing Locator mapping directly over
the Locator/ID Separation Protocol Alternative Topology (LISP-ALT), use the ipv6 lisp alt-vrf
command. To remove the reference to a VRF, use the no form of this command.

Usage Guidelines
that the LISP device should use for control plane mapping resolution functions.
You must use the ipv6 lisp alt-vrf command for all devices that connect to the ALT to exchange LISP
control plane messages for mapping. These devices include LISP Map-Server (MS), Map-Resolver
(MR), and Proxy Ingress Tunnel Router (PITR) devices, and directly ALT-connected xTRs.

Modification
This command was introduced.
The LISP ALT does not support virtualization. A Map-Request with an instance-id cannot be
forwarded over the LISP ALT. When you configure a LISP device for virtualization, you must not
sue the ipv6 lisp alt-vrf command.
When you configure instance IDs on an MS (see the LISP Site eid-prefix command), you must
configure the MS as a standalone because virtualization of the LISP ALT is not supported.
When you configure a Cisco NX-OS device as a standalone MS or MR without virtualization, you
need not use the ipv6 lisp alt-vrf command.
When you configure a Cisco NX-OS device as a LISP PITR, you can use the ip lisp alt-vrf
command if you are using the ALT for EID-to-RLOC mapping resolution. You can configure PITRs
to 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. When using a PITR in a
