Both N- and + * V-bits MUST NOT be set in the same packet.

This bit MUST be ignored + * and has no meaning when the N-bit is set to 0. When the N-bit is + * set to 1 and this bit is set to 1, an ITR is requesting that the + * nonce value in the 'Nonce' field be echoed back in LISP- + * encapsulated packets when the ITR is also an ETR. See + * Section 6.3.1 for details. + * + * V: The V-bit is the Map-Version present bit. When this bit is set to + * 1, the N-bit MUST be 0. Refer to Section 6.6.3 for more details. + * + * I: The I-bit is the Instance ID bit. See Section 5.5 for more + * details.

If the L-bit is set to 0, then the low-order + * 8 bits are transmitted as zero and ignored on receipt. + * + * P Bit: Flag bit 5 is defined as the Next Protocol bit. The P bit + * MUST be set to 1 to indicate the presence of the 8 bit next + * protocol field. + * + * P = 0 indicates that the payload MUST conform to LISP as defined + * in [RFC6830]. + * + * Flag bit 5 was chosen as the P bit because this flag bit is + * currently unallocated in LISP [RFC6830]. + * + * O: Flag bit 7 is defined as the O bit. When the O bit is set to 1, the + * packet is an OAM packet and OAM processing MUST occur. The OAM + * protocol details are out of scope for this document. As with the + * P-bit, bit 7 is currently a reserved flag in [RFC6830]. + * + * Next Protocol Field: The lower 8 bits of the first word are used to + * carry a next protocol. This next protocol field contains the + * protocol of the encapsulated payload packet. + * + * LISP [RFC6830] uses the lower 16 bits of the first word for either + * a nonce, an echo-nonce ([RFC6830]) or to support map-versioning + * ([RFC6834]). These are all optional capabilities that are + * indicated by setting the N, E, and the V bit respectively. + * + * To maintain the desired data plane compatibility, when the P bit + * is set, the N, E, and V bits MUST be set to zero. + * + * A new protocol registry will be requested from IANA for the Next + * Protocol field.

Expires January 5, 2015 [Page 2] + +Internet-Draft LISP Generic Protocol Extension July 2014 + + +1. Introduction + + LISP [RFC6830] defines an encapsulation format that carries IPv4 or + IPv6 (henceforth referred to as IP) packets in a LISP header and + outer UDP/IP transport. + + The LISP header does not specify the protocol being encapsulated and + therefore is currently limited to encapsulating only IP packet + payloads. Other protocols, most notably VXLAN [VXLAN] (which defines + a similar header format to LISP), are used to encapsulate L2 + protocols such as Ethernet. LISP [RFC6830] can be extended to + indicate the inner protocol, enabling the encapsulation of Ethernet, + IP or any other desired protocol all the while ensuring compatibility + with existing LISP [RFC6830] deployments. + + As LISP is deployed, there's also the need to provide increased + visibility and diagnostic capabilities within the overlay. + + This document describes extending LISP ([RFC6830]) via the following + changes: + + Next Protocol Bit (P bit): A reserved flag bit is allocated, and set + in the LISP-gpe header to indicate that a next protocol field is + present. + + OAM Flag Bit (O bit): A reserved flag bit is allocated, and set in + the LISP-gpe header, to indicate that the packet is an OAM packet. + + Version: Two reserved bits are allocated, and set in the LISP-gpe + header, to indicate LISP-gpe protocol version. + + Next protocol: An 8 bit next protocol field is present in the LISP- + gpe header. + + + + + + + + + + + + + + + + + + +Lewis, et al. Expires January 5, 2015 [Page 3] + +Internet-Draft LISP Generic Protocol Extension July 2014 + + +2. LISP Header Without Protocol Extensions + + As described in the introduction, the LISP header has no protocol + identifier that indicates the type of payload being carried by LISP. + Because of this, LISP is limited to an IP payload. Furthermore, the + LISP header has no mechanism to signal OAM packets. + + The LISP header contains flags (some defined, some reserved), a + Nonce/Map-version field and an instance ID/Locator-status-bit field. + The flags provide flexibility to define how the reserved bits can be + used to change the definition of the LISP header. + + + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + |N|L|E|V|I|flags| Nonce/Map-Version | + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + | Instance ID/Locator-Status-Bits | + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + + + Figure 1: LISP Header + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +Lewis, et al.

Multi Protocol Support + + This draft defines the following changes to the LISP header in order + to support multi-protocol encapsulation. + + P Bit: Flag bit 5 is defined as the Next Protocol bit. The P bit + MUST be set to 1 to indicate the presence of the 8 bit next + protocol field. + + P = 0 indicates that the payload MUST conform to LISP as defined + in [RFC6830]. + + Flag bit 5 was chosen as the P bit because this flag bit is + currently unallocated in LISP [RFC6830]. + + Next Protocol Field: The lower 8 bits of the first word are used to + carry a next protocol. This next protocol field contains the + protocol of the encapsulated payload packet. + + LISP [RFC6830] uses the lower 16 bits of the first word for either + a nonce, an echo-nonce ([RFC6830]) or to support map-versioning + ([RFC6834]). These are all optional capabilities that are + indicated by setting the N, E, and the V bit respectively. + + To maintain the desired data plane compatibility, when the P bit + is set, the N, E, and V bits MUST be set to zero. + + A new protocol registry will be requested from IANA for the Next + Protocol field. This draft defines the following Next Protocol + values: + + 0x1 : IPv4 + + 0x2 : IPv6 + + 0x3 : Ethernet + + 0x4: Network Service Header + + + + + + + + + + + +Lewis, et al.

A method for determining the capabilities of a + LISP router (gpe or "legacy") is out of the scope of this draft. + + When encapsulating IP packets to a LISP router the P bit SHOULD be + set to 1 and the UDP port MUST be set to 4341. OAM bit MUST be set + to 0. The Next Protocol field SHOULD be 0x1 (IPv4) or 0x2 (IPv6). + The (legacy) LISP router will ignore the P bit and the protocol type + field. The (legacy) LISP router will treat the packet as a LISP + packet and inspect the first nibble of the payload to determine the + IP version. + + When the P bit is set, the N, E, and V bits MUST be set to zero. The + receiving (legacy) LISP router will ignore N, E and V bits, when the + P bit is set. + +4.2. (legacy) LISP Routers to LISP-gpe Routers + + When a LISP-gpe router receives a packet from a (legacy) LISP router, + the P bit MUST not be set and the UDP port MUST be 4341. The payload + MUST be IP, and the LISP-gpe router will inspect the first nibble of + the payload to determine IP version. + +4.3. Type of Service + + When a LISP-gpe router performs Ethernet encapsulation, the inner + 802.1Q [IEEE8021Q] priority code point (PCP) field MAY be mapped from + the encapsulated frame to the Type of Service field in the outer IPv4 + header, or in the case of IPv6 the 'Traffic Class' field. + +4.4.
