more EID-prefixes and routing locators that the ETR is configured to use. After verifying the
authentication data, the Map Server checks the EID-prefixes against those configured on the
Map-Server. If they agree, the Map Register is accepted and the ETR registration is completed.

routing locators. To enable this functionality, enter the allowed-locator command in LISP site
configuration mode. The Map-Register message from the ETR must contain the same locators that are
listed in the Map-Server LISP site configuration. If the list in the Map Register does not match the one
configured on the Map Server, the Map-Register message is not accepted and the ETR is not registered.
You can configure up to four IPv4 or IPv6 routing locators.

Note
the Map Server within the LISP site configuration must also appear in the Map-Register message sent
by the ETR for it to be accepted.
