Cisco Confidential 5 LISP separates Endpoint IDentifiers (EIDs) from Routing LOCators (RLOCs) Both EIDs and RLOCs are represented with IP addresses (in two different name spaces) Applications/TCP on endpoints bind to EIDs Applications/TCP are unaware of LISP LISP Tunnel Routers resolve EIDs onto RLOCs by querying a distributed Mapping System Encapsulate/Decapuslate host-generated packets with RLOCs as outer addresses Route LISP encapsulated packets to reach destination RLOC
