LISP Parallel Model Virtualization Implementation Considerations and Caveats
Figure 13: LISP parallel model multitenancy case. Shared xTRs use virtualized core networks and mapping systems. LISP instance IDs
segment the LISP data plane and control plane.

LISPParallelModelVirtualizationImplementationConsiderationsandCaveats

When you use LISP parallel model virtualization, each vrfvrf vrf-name instantiation is considered by a separate
process. Instance IDs must be unique only within a vrf instantiation.

The vrf beta table is not available for use as an EID table (in use by switch lisp 1 EID
instance 101 VRF)
In the above example, four VRFs are created: alpha, beta, gamma, and delta, as follows:
• The vrf instantiation device lisp 1 is created and associated with the VRF named alpha.
• The EID VRF named beta is specified and associated with instance ID 101.
• A new vrf instantiation, device lisp 3, is created and associated with the locator-table VRF named gamma.
• The EID table VRF named delta is specified and also associated with instance ID 101.
