This example shows how to initiate a LIG operation for a destination EID or to test the router's local
Examples
EID prefix:
switch# lig self
Send loopback map-request to 128.223.156.35 for 153.16.12.0 ...
Received map-reply from 128.223.156.23 with rtt 0.002770 secs
Map-cache entry for EID 153.16.12.0:
153.16.12.0/24, uptime: 00:00:02, expires: 23:59:57, via map-reply, self
Locator

This example shows how to display the local IPv6 EID-prefix that is registered in the mapping database:
switch# lig self6
Send loopback map-request to 128.223.156.35 for 2610:d0:1203:: ...
Received map-reply from 128.223.156.23 with rtt 0.001148 secs
Map-cache entry for EID 2610:d0:1203:::
2610:d0:1203::/48, uptime: 00:00:02, expires: 23:59:57, via map-reply, self
Locator

This example shows how to display all LISP map-cache entries, and then uses lig to test for the remote
IPv6 EID-prefix:
switch# show ipv6 lisp map-cache
LISP IPv6 Mapping Cache for VRF "default", 0 entries
This example show to to configure LIG to test for the remote IPv6 EID-prefix:

By default, at a minimum, one Map-Request is sent to the Map-Resolver but up to three
Map-Requests might be sent to the Map-Resolver. Once a Map-Reply is returned for a Map-Request,
no further Map-Requests are sent. When you apply the count option, a specified number of
Map-Requests is sent.
By default, the source of the Map-Request is the first configured EID-prefix for the site (with the
host-bit set to zero). For example, if the local EID-prefix is 153.16.21.0/24, the source EID is
153.16.21.0 for the Map-Request. When the source option is applied, a specific source EID might
be used. However, the source-EID must be one of the EID addresses assigned to the LISP router.
When the lig command is used with the self option, the destination IPv4 EID is also the first
configured EID-prefix for the site (with the host-bit set to zero). For example, if the local IPv4
EID-prefix is 153.16.21.0/24, the destination EID is 153.16.21.0 for the Map-Request. Use the self6
option for IPv6 addresses.
By default, when you enter the lig command, the Map-Request is sent to the configured
Map-Resolver. However, the to option can be specified to cause the Map-Request to be forwarded
to a specified Map-Resolver instead. Sending a Map-Request to a different Map-Resolver can be
useful to test that your EID-prefix has been properly injected into the ALT infrastructure. In this
case, the lig Map-Request is processed by the specified Map-Resolver and propagated through each
ALT router hop to the Map-Server you have registered to. The Map-Server returns the Map-Request
to your site. Your site generates a Map-Reply to the source of the Map Request (which could be itself
or a different xTR within your LISP site).
