LISP Shared Model Virtualization Implementation Considerations and Caveats

Figure 10: LISP shared model multitenancy use case. Customer's use shared xTRs and share a common core network and mapping
system.
LISP Shared Model Virtualization Implementation Considerations and Caveats
When you use the LISP Shared Model, instance IDs must be unique to an EID VRF.
xTR-1# configure terminal
xTR-1(config)# vrf context alpha
xTR-1(config-vrf)# lisp instance-id 101
xTR-1(config-vrf)# exit
xTR-1(config)# vrf context beta
xTR-1(config-vrf)# lisp instance-id 101
Instance-ID 101 is already assigned to VRF context alpha
In the example, two EID VRFs are created: alpha and beta. In global configuration mode, a VRF named alpha
is specified and associated with the instance ID 101. Next, a VRF named beta is specified and also associated
with the instance ID 101. This configuration is not permissible because instance ID 101 is already associated
with the VRF context named alpha. That is, you cannot connect the same instance ID to more than one EID
VRF.

LISP Parallel Model Virtualization

The LISP parallel model virtualization ties the virtualized EID space associated with VRFs to RLOCs that
are associated with the same or different VRFs (see the following figure).
