Introduction The LISP architecture [RFC6830] specifies two namespaces, End-Point IDs (EIDs) and Routing Locators (RLOCs). An EID identifies a node in the network and the RLOC indicates the EID's topological location. + Typically EIDs are globally unique so an end-node system can connect to any other end-node system on the Internet. Privately used EIDs are allowed when scoped within a VPN but must always be unique within that scope. Therefore, address allocation is required by network administration to avoid address collisions or duplicate address use. In a multiple namespace architecture like LISP, typically the EID will stay fixed while the RLOC can change. This occurs when the EID is mobile or when the LISP site the EID resides in changes its connection to the Internet. @@ -343,120 +344,126 @@ 11.2.
