Correct answer: Map Resolver.
Why this is the answer
The Map Resolver (MR) is responsible for receiving LISP encapsulated packets from Ingress Tunnel Routers (ITRs) and then querying the mapping system to find the Egress Tunnel Router (ETR) for the destination Endpoint Identifier (EID). It then forwards this mapping information to the requesting ITR. Router Locator (RLOC) is an IP address of a router, not a function. A Proxy ETR (PETR) is a router that acts as an ETR for non-LISP sites. An Ingress Tunnel Router (ITR) encapsulates packets from a site and sends them into the LISP cloud.
