When you configure LISP database parameters on an ITR for specified IPv4 EID-prefix blocks by using
Usage Guidelines
the ipv6 lisp database-mapping command or the ipv6 lisp map-cache command, the locators
associated with these IPv4 EID-prefix blocks are considered as reachable (up) by default. You can use
the ipv6 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 ipv6 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 ipv6 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.
