ip lisp source-locator

To configure a source locator to be used for IPv4 Locator/ID Separation Protocol (LISP)-encapsulated
packets, use the ip lisp source-locator command. To remove the configured source locator, use the no
form of this command.

When sending a LISP-encapsulated packet (data or control message), Cisco NX-OS device performs a
Usage Guidelines
destination lookup to determine the appropriate outgoing interface. By default, the IPv4 address of this
outgoing interface is used as the source locator for the outbound LISP encapsulated packet.
In some circumstances, you might need to use the IPv4 address of a different interface as the source
locator for the outbound LISP encapsulated packets rather than that of the outgoing interface. For
example, when an ITR has multiple egress interfaces, you might configure a loopback interface for
stability purposes and instruct the ITR to use the address of this loopback interface as the source locator
for the outbound LISP-encapsulated packets rather than one or both of the physical interface addresses.
The use of this command is also important for maintaining locator consistency between the two xTRs
when rloc-probing is used.
This command does not require a license.
This example shows how to configure the source locator:
Examples
switch# configuration terminal
switch(config)# interface Ethernet2/0
switch(config-if)# ip lisp source-locator Loopback0
switch(config-if)# interface Ethernet2/1
OL-25345-01
ip lisp source-locator interface
no ip lisp source-locator interface
Name of the interface whose IPv4 address should be used as the source locator
address for outbound LISP-encapsulated packets.
