ip lisp map-request-source

To configure an IPv4 or IPv6 address to be used as the source address for Locator/ID Separation Protocol
(LISP) IPv4 Map-Request messages, use the ip lisp map-request-source command. To remove the
configured Map-Request source address and return to the default behavior, use the no form of this
command.
Syntax Description source-address

Usage Guidelines
source address for LISP IPv4 Map-Request messages. There are cases, however, where it may be
necessary to configure the specified source address for these Map-Request messages. For example, when
the ingress tunnel router (ITR) is behind a NAT device, you might need to specify a source address that
matches the NAT configuration to properly allow for return traffic.
When you enter the ip lisp map-request-source command on an ITR, the specified IPv4 or IPv6 locator
is used by an ITR as the source address for LISP IPv4 Map-Request messages. When you enter the ip
lisp map-request-source command on a Map-Server, this locator is used as the source address in the
Encapsulated Control Message that carries a Map-Request to an ETR.
This command does not require a license.
This example shows how to configure an ITR to use the source IP address 172.16.1.7 in its IPv4
