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 - */ - -/** LISP-GPE header */ -typedef struct -{ - u8 flags; - u8 ver_res; - u8 res; - u8 next_protocol; - u32 iid; -} lisp_gpe_header_t; - -#define foreach_lisp_gpe_flag_bit \ -_(N, 0x80) \ -_(L, 0x40) \ -_(E, 0x20) \ -_(V, 0x10) \ -_(I, 0x08) \ -_(P, 0x04) \ -_(O, 0x01) - -typedef enum -{ -#define _(n,v) LISP_GPE_FLAGS_##n = v, - foreach_lisp_gpe_flag_bit -#undef _ -} vnet_lisp_gpe_flag_bit_t; - -#define LISP_GPE_VERSION 0x0 - -#define LISP_GPE_NEXT_PROTOCOL_IP4 0x1 -#define LISP_GPE_NEXT_PROTOCOL_IP6 0x2 -#define LISP_GPE_NEXT_PROTOCOL_ETHERNET 0x3 -#define LISP_GPE_NEXT_PROTOCOL_NSH 0x4 - -typedef enum -{ - LISP_GPE_NEXT_PROTO_IP4 = 1, - LISP_GPE_NEXT_PROTO_IP6, - LISP_GPE_NEXT_PROTO_ETHERNET, - LISP_GPE_NEXT_PROTO_NSH, - LISP_GPE_NEXT_PROTOS -} lisp_gpe_next_protocol_e; - -#endif /* included_lisp_gpe_packet_h */ - -/* - * fd.io coding-style-patch-verification: ON - * - * Local Variables: - * eval: (c-set-style "gnu") - * End: - */ diff --git a/src/vnet/lisp-gpe/lisp_gpe_sub_interface.c b/src/vnet/lisp-gpe/lisp_gpe_sub_interface.c deleted file mode 100644 index 1ccd5817d7f..00000000000 --- a/src/vnet/lisp-gpe/lisp_gpe_sub_interface.c +++ /dev/null @@ -1,286 +0,0 @@ -/* - * Copyright (c) 2016 Cisco and/or its affiliates. - * Licensed under the Apache License, Version 2.0 (the "License"); - * you may not use this file except in compliance with the License. - * You may obtain a copy of the License at: - * - * http://www.apache.org/licenses/LICENSE-2.0 - * - * Unless required by applicable law or agreed to in writing, software - * distributed under the License is distributed on an "AS IS" BASIS, - * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. - * See the License for the specific language governing permissions and - * limitations under the License. - */ -/** - * @file - * @brief LISP sub-interfaces. - * - */ -#include <vnet/lisp-gpe/lisp_gpe_tenant.h> -#include <vnet/lisp-gpe/lisp_gpe_sub_interface.h> -#include <vnet/fib/fib_table.h> -#include <vnet/interface.h> - -/** - * @brief Pool of all l3-sub-interfaces - */ -static lisp_gpe_sub_interface_t *lisp_gpe_sub_interface_pool; - -/** - * A DB of all LISP L3 sub-interfaces.

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.

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.

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.

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. - - - - -Lewis, et al.
