ipv6 lisp nat-transversal

To configure an egress tunnel router (ETR) with a private locator that is sited behind a Network Address
Translation (NAT) device to dynamically determine its NAT-translated public locator for use in
Map-Register and Map-Reply messages, use the ip lisp nat-transversal command. To remove this
functionality, use the no form of this command.
This command has no arguments or keywords.

When an ETR is sited behind a NAT device, its routing locator belongs to the private address space that
Usage Guidelines
the NAT device translates to a public globally routed address. The ETR needs to know this public global
locator address because this address is required for use in Map-Register and Map-Reply messages.
When you enter the ip lisp nat-transversal command is configured, the ETR determines its own public
global locator dynamically. When configured, the ETR sends a LISP Echo-Request message to the
configured Map Server out the interface under which this command is configured. The Map Server
replies with an Echo Reply message that includes the source address from the Echo Request, which is
the NAT-Translated public global locator address.
The ipv6 lisp nat-transversal command is useful when the dynamic keyword is used with the ipv6 lisp
database-mapping command in order to dynamically determine the routing locator rather than statically
defining it.
This command does not require a license.
This example shows how to configure the ETR to dynamically determine its public global routing locator
