Configuring Simple LISP Parallel Model Virtualization
• Each LISP xTR has a single RLOC connection to a parallel IPv4 core network.
Perform the steps in this task (once through for each xTR in the LISP site) to enable and configure LISP ITR
and ETR (xTR) functionality when using a LISP map-server and map-resolver for mapping services. The
example configurations at the end of this task show the full configuration for two xTRs (Left-xTR and
Right-xTR).
Before you begin
Create the VRFs using the vrf context command.

LISP Instance-ID Support
Purpose
Enters global configuration mode.
Enters VRF configuration submode.
• In this example, the RLOC VRF named
vrf1 is configured.
Configures an association between a VRF and
a LISP instance ID.
Configures an EID-to-RLOC mapping
relationship and its associated traffic policy
for this LISP site.
Note In this example, a single IPv4 EID
prefix, 192.168.1.0/24, within
instance ID 1 at this site is
associated with the local IPv4
RLOC 10.0.0.2.
Exits VRF configuration submode and returns
to global mode.
Configures a locator address for the LISP map
resolver to which this switch will send map
request messages for IPv4 EID-to-RLOC
mapping resolutions.
