The LISP control plane works in a similar way to DNS.
As DNS changes a domain name into an IP address, LISP resolves an endpoint identifier (EID) into a routing locator (RLOC) by sending a request to a map resolver (MR)
This means that LISP is built as a pull model, it only gains the routing information that is requested, rather than a push model where all information, including irrelevant information, is sent to the device.
