UPC/BarcelonaTech March 5, 2020 The Locator/ID Separation Protocol (LISP) - draft-ietf-lisp-rfc6830bis-31 + draft-ietf-lisp-rfc6830bis-32 Abstract This document describes the Data-Plane protocol for the Locator/ID Separation Protocol (LISP). LISP defines two namespaces, End-point Identifiers (EIDs) that identify end-hosts and Routing Locators (RLOCs) that identify network attachment points. With this, LISP effectively separates control from data, and allows routers to create overlay networks. LISP-capable routers exchange encapsulated packets according to EID-to-RLOC mappings stored in a local Map-Cache. @@ -855,21 +855,21 @@ misconfiguration. Some xTRs and PxTRs performs re-encapsulation operations and need to treat the 'Explicit Congestion Notification' (ECN) in a special way. Because the re-encapsulation operation is a sequence of two operations, namely a decapsulation followed by an encapsulation, the ECN bits MUST be treated as described above for these two operations. The LISP dataplane protocol is not backwards compatible with [RFC6830] and does not have explicit support for introducing future - protocol changes (e.g. an explicit version field), However, the LISP + protocol changes (e.g. an explicit version field). However, the LISP control plane [I-D.ietf-lisp-rfc6833bis] allows an ETR to register dataplane capabilities by means of new LCAF types [RFC8060]. In this way an ITR can be made aware of the dataplane capabilities of an ETR, and encapsulate accordingly. The specification of the new LCAF types, new LCAF mechanisms, and their use, is out of the scope of this document. 6.
