Configuring Large-Scale LISP Shared Model Virtualization

Step 14
Configuring Large-Scale LISP Shared Model Virtualization
To implement LISP shared model virtualization, you can configure LISP ITR/ETR (xTR) functionality with
LISP map server and map resolver. This LISP shared model reference configuration is for a large-scale,
multiple-site LISP topology, including xTRs and multiple MS/MRs.
This procedure is for an enterprise that is deploying the LISP Shared Model where EID space is virtualized
over a shared, common core network. A subset of the entire network is shown in the following figure. Three
sites are shown: a multihomed "Headquarters" (HQ) site, and two remote office sites. The HQ site switches
are deployed as xTRs and also as map resolver/map servers. The remote sites switches act as xTRs, and use
the MS/MRs at the HQ site for LISP control plane support.

Command or Action
clear [ip | ipv6] lisp map-cache [vrf vrf-name]
Example:
The first command displays IPv4 mapping
cache information for vrf1. The second
command clears the mapping cache for vrf1
and displays the updated status.
switch(config)# show ip lisp map-cache
vrf vrf1
switch(config)# clear ip lisp map-cache
vrf vrf1
LISP Instance-ID Support
Purpose
The clear ip lisp map-cache and clear ipv6
lisp map-cache commands remove all IPv4
or IPv6 dynamic LISP map-cache entries
stored by the switch, respectively. They also
show the operational status of the LISP control
plane. This command applies to a LISP switch
that maintains a map cache (for example, a
switch configured as an ITR or PITR).
