database-mapping to be unreachable (down), use the ip lisp locator-down command. To return the
locator to be reachable (up), remove the configuration using the no form of this command.

When you configure LISP database parameters on an ITR for specified IPv4 EID-prefix blocks by using
Usage Guidelines
the ip lisp database-mapping command or the ip lisp map-cache command, the locators associated
with these IPv4 EID-prefix blocks are considered as reachable (up) by default. You can use the ip lisp
locator-down command to configure a locator from a locator-set associated with the EID-prefix
database mapping to be down.
When you enter the ip lisp locator-down command, the Locator Status Bits (LSB) for the configured
locator is cleared when encapsulating packets to remote sites. ETRs at remote sites look for changes in
the LSB when decapsulating LISP packets, and when the LSB indicates that a specific locator is down,
the ETR refrains from encapsulating packets using this locator to reach the local site.
If you enter the ip lisp locator-down command on an ITR to indicate that a locator is unreachable
Note
(down) and the LISP site includes multiple ITRs, you must enter the ip lisp locator-down command on
all ITRs at the site to ensure that the site consistently tells remote sites that the configured locator is not
reachable.
This command does not require a license.
