How To Configure Lisp Instance-Id Support; Configuring Simple Lisp Shared Model Virtualization - Cisco Nexus 7000 Series Configuration Manual

LISP Instance-ID Support
These two instance IDs are unrelated to each other; one is relevant only within device lisp 1, and the other is
relevant only within device lisp 2.
In the example, note that under device lisp 2, the code requests a VRF instance named beta. Note that the
device is unable to use this VRF instance because it (beta) is already associated with a vrf command within
the device lisp 1 instantiation.
You can reuse an instance ID. The EID VRF into which it is decapsulated depends on the vrf instantiation
with which it is associated. However, you cannot connect the same EID VRF to more than one VRF.

Configuring Simple LISP Shared Model Virtualization

You can perform this task to enable and configure LISP ingress tunnel router/egress tunnel router (ITR/ETR)
functionality (also known as xTR) with the LISP map server and map resolver, and thereby implement LISP
shared model virtualization. This LISP shared model reference configuration is for a very simple two-site
LISP topology, including xTRs and an map server/map resolver (MS/MR).
The following figure shows a basic LISP shared model virtualization solution. Two LISP sites are deployed,
each containing two VRFs: PURPLE and GOLD. LISP is used to provide virtualized connectivity between
these two sites across a common IPv4 core, while maintaining address separation between the two VRF
instances.
Figure 14: Simple LISP Site with Virtualized IPv4 and IPv6 EIDs and a Shared IPv4 core
In this figure, each LISP site uses a single edge switch that is configured as both an ITR and ETR (xTR), with
a single connection to its upstream provider. The RLOC is IPv4, and IPv4 and IPv6 EID prefixes are configured.
Each LISP site registers to a map server/map resolver (MS/MR) switch that is located in the network core
within the shared RLOC address space.
