- * equivalent to the usal adjacency key {next-hop, interface}. So curiously
- * the rloc address from the underlay is used as a next hop address in the overlay
- * This is OK because:

- * overlay
- * 2 - the RLOC may overlap with an address in the overlay, but we do not create
- * an adj-fib (i.e. a route in the overlay FIB for the rloc)

- * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- *
- * N: The N-bit is the nonce-present bit. When this bit is set to 1,
- * the low-order 24 bits of the first 32 bits of the LISP header
- * contain a Nonce. See Section 6.3.1 for details. Both N- and
- * V-bits MUST NOT be set in the same packet. If they are, a
- * decapsulating ETR MUST treat the 'Nonce/Map-Version' field as
- * having a Nonce value present.
- *
- * L: The L-bit is the 'Locator-Status-Bits' field enabled bit. When
- * this bit is set to 1, the Locator-Status-Bits in the second
- * 32 bits of the LISP header are in use.
- *
- * E: The E-bit is the echo-nonce-request bit. 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. When this bit is set to 1, the 'Locator-Status-Bits'
- * field is reduced to 8 bits and the high-order 24 bits are used as
- * an Instance ID. 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. This draft defines the following Next Protocol
- * values:
- *
- * 0x1 : IPv4
- * 0x2 : IPv6
- * 0x3 : Ethernet
- * 0x4: Network Service Header

-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.

-
-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.

-3. Generic Protocol Extension for LISP (LISP-gpe)
-
-3.1. 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

-
-3.2. OAM Support
-
- 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].

-3.3. Version Bits
-
- LISP-gpe bits8 and 9 are defined as version bits. The version field
- is used to ensure backward compatibility going forward with future
- LISP-gpe updates.
-
- The initial version for LISP-gpe is 0.

-
-4. Backward Compatibility
-
- Undefined (in RFC6830) flag bits 5 and 7, LISP-gpe P and O bits, were
- selected to ensure compatibility with existing LISP [RFC6830]
- deployments.
-
- Similarly, using P = 0 to indicate that the format of the header and
- payload conforms to [RFC6830] ensures compatibility with existing
- LISP hardware forwarding platforms.
-
-4.1. LISP-gpe Routers to (legacy) LISP Routers
-
- A LISP-gpe router MUST not encapsulate non-IP packet nor OAM packets
- to a LISP router. 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. VLAN Identifier (VID)
-
- When a LISP-gpe router performs Ethernet encapsulation, the inner
- header 802.1Q [IEEE8021Q] VLAN Identifier (VID) MAY be mapped to, or
- used to determine the LISP Instance ID field.

-6. Security Considerations
-
- LISP-gpe security considerations are similar to the LISP security
- considerations documented at length in LISP [RFC6830]. With LISP-
- gpe, issues such as dataplane spoofing, flooding, and traffic
- redirection are dependent on the particular protocol payload
- encapsulated.

-8. IANA Considerations
-
- IANA is requested to set up a registry of "Next Protocol". These are
- 8-bit values. Next Protocol values 0, 1, 2, 3 and 4 are defined in
- this draft. New values are assigned via Standards Action [RFC5226].
-
- +---------------+-------------+---------------+
- | Next Protocol | Description | Reference |
- +---------------+-------------+---------------+
- | 0 | Reserved | This document |
- | | | |
- | 1 | IPv4 | This document |
- | | | |
- | 2 | IPv6 | This document |
- | | | |
- | 3 | Ethernet | This document |
- | | | |
- | 4 | NSH | This document |
- | | | |
- | 5..253 | Unassigned | |
- +---------------+-------------+---------------+
-
- Table 1
-
- There are ten bits at the beginning of the LISP-gpe header. New
- bits are assigned via Standards Action [RFC5226].
-
- Bits 0-3 - Assigned by LISP [RFC6830]
- Bit 4 - Instance ID (I bit)
- Bit 5 - Next Protocol (P bit)
- Bit 6 - Reserved
- Bit 7 - OAM (O bit)
- Bits 8-9 - Version
