In a Locator/ID Separation Protocol (LISP) routing architecture, the Egress Tunnel Router (ETR) is responsible for receiving and de-encapsulating LISP traffic for endpoints within a LISP-capable site. The ETR registers its EID prefixes and RLOCs with the Map-Server and responds to map requests received from the Map-Server. On the data plane side, an ETR receives packets from core-facing interfaces, de-encapsulates them, and delivers them to local EIDs at the site.
