Introduction

To ensure the smooth and cost-efficient uptake of IPv6 across their networks, it is important that governments and large enterprises specify requirements for IPv6 compatibility when seeking tenders for information and computer technology Information and Communication Technology (ICT) equipment and support. This document is intended to provide a Best Common Practice (BCP) Current Practice (BCP) and does not specify any standards or policy itself.It can serve as a template that can be used by governments or large enterprises when developing tender documents. governments, large enterprises and all other organisations when seeking IPv6 support in their tenders or equipment requirements and offer guidance on what specifications to ask for. It can also serve as an aid to those people or organisations interested in tendering for government or enterprise contracts.

  1. Formulating requirements for IPv6 support can be done in several ways. In this document we look at three different options:

    Option 1 is based loosely

    Be aware that the standards listed here have their origin in various bodies, which operate independent of the RIPE community, and that any of these standards might be changed or become replaced with a newer version. You may also need to adjust the recommendations to your specific local needs.

    Some parts of this section are loosely based on the NIST/USGv6 profile developed by the US government Link: http://www.antd.nist.gov/usgv6/ . The go6 expert council and the Slovenian IPv6 working group government[1]: http://www.antd.nist.gov/usgv6/ Link: http://www.antd.nist.gov/usgv6/ The authors have modified these documents to make them more universally applicable. The new draft This option includes a list of RFC specification standards which that must be supported, divided into four eight categories of devices.
  2. Option 2 is based on compliance with the “IPv6 Ready” program, as specified by the IPv6 Forum. This program is divided into two phases: Phase 1 includes testing and certification of the basic "core" protocols, while Phase 2 includes testing and certification of advanced IPv6 functionality.
  3. Option 3 is a combination of the first two approaches.

    4. Option 1

    Requirements are divided in equipment and integrator support (output from go6 IPv6 WG).

    The following is the draft text that we propose be included in public tenders for ICT equipment, specifying requirements for IPv6 capability and support:

This document also follows the IPv6 Node requirements document, RFC6434. This RFC is the general IETF guidance on what parts of IPv6 need to be implemented by different devices.

General information on how to use this document

An IPv6 Ready Logo certificate can be required for any device. This is the easiest way for vendors providing the equipment to prove that it fulfills basic IPv6 requirements. The tender initiator shall also provide the list of required mandatory and optional RFCs in order not to exclude vendors that did not yet put their equipment under IPv6 Ready Logo testing certifications. This way public tenders can't be accused of preferring any type or vendor of equipment.

When we specify the list of required RFCs, we must list all mandatory requirements, except the entries that start with, “If [functionality] is requested…” These entries are mandatory only if the tender initiator requires certain functionality. Please note that the tender initiator should decide what functionality is required, not the equipment vendor.

Certain features that are in the 'optional' section in this document might be important for your specific case and/or organisation. In such cases the tender initiator should move the requirement to the 'required' section in their tender request.

How to specify requirements

As stated above, the IPv6 Ready Logo program does not cover all equipment that correctly supports IPv6; so declaring such equipment ineligible may not be desirable. This document recommends that the tender initiator specify that eligible equipment be either certified under the IPv6 Ready program or be compliant with the appropriate RFCs listed in the section below.

About the IPv6 Ready Logo program: https://www.ipv6ready.org/ Link: https://www.ipv6ready.org/

Also note that there exists the BOUNDv6 project whose goal is to create a permanent multi-vendor network environment connecting approved laboratories where the community can test IPv6-enabled applications and devices in meaningful test scenarios. Tender initiators are encouraged to have a look and also use the results of this project.

About BOUNDv6: http://www.boundv6.org/

Important note for tender initiator:

The IPv6 Ready Logo certification covers basic IPv6 requirements and some advanced features, but not all of them. If you require any advanced feature that is not covered by IPv6 Ready Logo certification, please request a list of RFCs that covers those specific needs in addition to IPv6 Logo Certification. In the lists below RFCs that are covered in the IPv6 Ready Logo certification are marked with *.

Proposed generic text for the tender initiator

In every tender, following text shall be included:

All ICT hardware as subject of this tender must support both the IPv4 and IPv6 protocols. Similar performance must be provided for both protocols. There should not be more than ...% difference protocols in input, output and/or throughput data-flow performance, transmission and processing of packets between the two protocols.

(Notes for tender initiators: For high-end devices we recommend to state a maximum difference of 15%. For enterprise grade devices we recommend a maximum of 30%. For consumer grade devices we recommend a maximum of 40%.)

packets.

IPv6 support can be verified and certified by the IPv6 Ready Logo certificate.

Any software that communicates via the IP protocol must support both protocol versions (IPv4 and IPv6). The difference must not be noticeable to users.

Requirements for support of standards

Equipment that has not been put through the IPv6 Ready testing procedures must comply with the RFCs listed below:

[appropriate list of selected mandatory and optional RFCs from below lists]

Lists of mandatory and optional RFC/3GPP technical specifications support for various hardware and software

Requirements are divided by hardware equipment and integrator support.

It should be assumed that all IPv4 traffic will migrate to IPv6. All requirements placed on IPv4 traffic capabilities like latency, bandwidth and throughput should also be required for IPv6 traffic.

IPsec: mandatory or optional

In the original IPv6 Node Requirements (RFC4294) standard, IPsec was listed as a 'MUST' implement to be standards compliant. The updated RFC (RFC6434) changed IPsec to a 'SHOULD' implement. Reasons for the change are stated in this new RFC.

The RIPE IPv6 Working Group has extensively discussed whether to make IPsec support mandatory or optional. The most vocal constituents showed support for moving IPsec to the optional sections, which is what is reflected in this document.

While the consensus of the community was to make IPsec optional in most cases, the IETF have now stated that IPsec 'SHOULD' be implemented in the latest version of the IPv6 Node Requirements standard (RFC6434). In the IETF context, a SHOULD means that there may exist valid reasons in particular circumstances to ignore a particular item, but the full implications must be understood and carefully weighed before choosing a different course.

Organisations that use IPsec or expect to use it in the future should include the following in the mandatory section when initiating the tender:

  • IPsec/IKEv2 [RFC4301, RFC4303, RFC4302, RFC5996] *

Definitions and descriptions of different types of devices

The following definitions will be used for classifying the varying hardware equipment. While some hardware may have overlapping functionality (i.e., a Layer 2 switch can act as a Layer 3 router or a router may have some firewall capabilities), it is expected that for any overlapping functionality, the requirements for each specific device be combined.

Host: A host is a network participant that sends and receives packets but does not forward them on behalf of others.

Switch, or ‘Layer 2 Switch': A switch or ‘Layer 2 switch' is a device that is primarily used for forwarding Ethernet frames based on their attributes. Exchanging Ethernet information with other Ethernet switches is usually part of its function.

Router or ‘Layer 3 Switch': A router or ‘Layer 3 switch' is a device that is primarily used for forwarding IP packets based on their attributes. Exchanging routing information with other Routers is usually part of its function.

Network Security Equipment: Network security equipment is devices whose primary function is to permit, deny and/or monitor traffic between interfaces in order to detect or prevent potential malicious activity. These interfaces can also include VPNs (SSL or IPsec). Network Security Equipment is often also a Layer 2 switch or a Router/Layer 3 switch.

Customer Premise Equipment (CPE): A CPE device is a small office or residential router that is used to connect home users and/or small offices in a myriad of configurations. Although a CPE is usually a Router, the requirements are different from an Enterprise/ISP Router Layer 3 switch.

Mobile Device: In the context of this document, a mobile device is a node that connects to a 3GPP defined system using some 3GPP specified access technology (such as 2G, 3G, or LTE). For situations where the network logic is being provided solely by a dedicated device A connected to another device B, the specification will refer to device A and not to device B. If the protocol logic is distributed (e.g. a computer with an external Ethernet interface that performs TCP checksum offloading), the aggregate system is being referred to.

Load Balancer: A load balancer is a networking device that distributes workload across multiple computers, servers or other resources, to achieve optimal or planned resource utilisation, maximise throughput, minimise response time, and avoid overload.

The following references are of relevance to this BCP document. At the time of publication, the editions indicated were valid. All references are subject to revision; users of this BCP document are therefore encouraged to investigate the possibility of applying the most recent edition of the references listed below.

Lists of required RFC/3GPP standards for different types of hardware

ICT hardware equipment can be roughly divided into four is divided into seven functional groups:

  • Host: client or server
  • Layer 2 switch
  • Router or layer 3 switch
  • Equipment to ensure network security (firewalls, IDS, IPS, ...)
    • Layer 3 switch
  • Network security equipment (firewalls, IDS, IPS...)
  • CPE
  • Mobile device
  • Load balancer

We have divided the following requirements into two categories, “mandatory” and “optional”. Equipment must meet the mandatory standards requirements list. Support for the optional requirements may earn the tender applicant additional points, if so specified by the tender initiator.

Please note that all RFC references are correct at the time of writing, but may be superseded by developments in the IETF. For all updates, please see: http://www.rfc-editor.org/ Link: http://www.rfc-editor.org/

Hardware

Any hardware that does not comply to with all of the mandatory standards is marked as inappropriate. should be marked as inappropriate by the tender evaluator.

The standards that are part of the IPv6 Ready Logo test procedures, typically performed by accredited labs, are marked with an asterisk *.

    A Network Security Device is often placed where a Layer 2 switch or a router/Layer 3 switch would otherwise be placed. Depending on this placement those requirements should be included.

    Functionality and features that are supported over IPv4 should be comparable with the functionalities functionality supported over IPv6. For example, if an intrusion prevention system is capable of operating over IPv4 in Layer 2 and Layer 3 mode, then it should also offer this functionality over IPv6. Or if a firewall is running in a cluster capable of synchronizing synchronising IPv4 sessions between all members of a cluster, then this must also be possible with IPv6 sessions.

      Requirements for load balancers

      A load balancer distributes incoming requests and/or connections from clients to multiple servers. Load balancers will have to support several combinations of IPv4 and IPv6 connections:

      • Load balancing IPv6 clients to IPv6 servers (6-to-6) must be supported
      • Load balancing IPv6 clients to IPv4 servers (6-to-4) must be supported
      • Load balancing IPv4 clients to IPv4 servers (4-to-4) should be supported
      • Load balancing IPv4 clients to IPv6 servers (4-to-6) should be supported
      • Load balancing a single external/virtual IPv4 address to a mixed set of IPv4 and IPv6 servers should be supported
      • Load balancing a single external/virtual IPv6 address to a mixed set of IPv4 and IPv6 servers should be supported

      If a load balancer provides Layer 7 (application level / reverse proxy, defined as ‘surrogate' in section 2.2 of RFC3040) load balancing then support for the X-forwarded-for (or equivalent) header in HTTP must be provided in order to make the source IP address of the client visible to the servers.

    Requirements for IPv6 support in software

    All software must support IPv4 and IPv6 and be able to communicate over both types of IPv4-only, IPv6-only and dual-stack networks. If software includes network parameters in its local or remote server settings, it should also support configuration of IPv6 parameters.

    Functional differences must not be significantly different between IPv4 and All features that are offered over IPv4 must also be available over IPv6. The user should not experience any significant noticeable difference when software is communicating over IPv4 or IPv6. IPv6, unless this is providing explicit benefit to the user.

    It is strongly recommended not to use any address literals in software code, as described in “Default Address Selection for Internet Protocol version 6” [RFC3484].

    Skill requirements of the systems integrator

    Vendors and reseller resellers that offer system integration services must have at least three employees who have valid certificates of competency from the equipment manufacturers for the equipment that is sold as part of the tender. These certificates must indicate a employees must also have general knowledge of the IPv6 protocol, IPv6 network planning and IPv6 security. security (as also indicated by the certification for these skills). If it becomes obvious during the equipment installation and integration that the integrator's knowledge, competence and experience is not sufficient to successfully install and configure the equipment to establish normal IPv4 and IPv6 communication with the network, the agreement shall be cancelled canceled and become null and void.

    The definition of proper integration, timing and degree of disruption of the network during the assembly shall be a matter of agreement between the client and systems integrator.

    It is also recommended that a systems integrator and its employees have a broad knowledge of IPv6 and generic IPv6 certificates other than those specifically offered by the equipment manufacturers. These certificates can be obtained from independent education providers. Such knowledge may be awarded extra points in the tender process.

    All bidders in the tender process must sign the following form, a declaration, which indicates that the company and its employees have passed technical training for design, construction and integration of ICT equipment in IPv4 and IPv6 networks.

    DECLARATION

    Declaration of technical competence for planning, building and integrating ICT equipment in IPv4 and IPv6 networks and environments

    Company: ________________________________________

    Address: ________________________________________

    declares, A sample of such a declaration is shown below.

    Declaration of IPv6 competence

    Tender initiators should require technical IPv6 competence declaration from the equipment supplier or integrator. IPv6 knowledge and experience is required to assure proper installation and integration of IPv6 in the ICT environment.

    The declaration should say that the equipment supplier or system integrator declares under criminal and material responsibility:

    • That we they have a sufficient number of people employed to perform offered services;
    • That those employees are professionally trained for their work - design, construction and integration of ICT equipment in both IPv4 and IPv6 networks and environments environments;
    • That the quality of offered services meets the requirements laid out in the tender documents.

      Place ____________________

      Date ____________________

      Stamp and signature of Systems Integrator

      Option 2

      The tender initiator can require ICT equipment to be “Phase 1” or “Phase 2” certified under the “IPv6 Ready” program. Tests for both phases of certification can be done in five accredited laboratories around the world: TTA (Korea), BII (China), CHT-TL (Taiwan), IRISA (France) and UNH-IOL (US). These tests determine basic IPv6 protocols compliance (Phase 1, approximately 150 tests) and advanced IPv6 functionality (Phase 2, over 450 tests).

      Any other requirements for the system integrator remain the same as in the first option.

      Proposed text for the tender initiator:

      ICT equipment that supports and communicates over the IPv4 protocol must also support the IPv6 protocol and be able to communicate with other devices over IPv6. Basic IPv6 support must be verified and certified by the IPv6 Ready program with a “Phase 1” logo certificate. A “Phase 2” logo certificate will be awarded additional points (+10%) in the tender evaluation procedure.

      Option 3

      The third option is a mix of the two alternatives outlined above. The IPv6 Ready program does not cover all equipment that correctly supports IPv6, so declaring such equipment ineligible may not be desirable. This option suggests that the tender initiator specify that eligible equipment may be either Phase 1 or Phase 2 certified under the IPv6 Ready program, or be compliant with the appropriate RFCs listed in Option 1.

      Proposed text for the tender initiator:

      ICT equipment that supports and communicates over the IPv4 protocol must also support the IPv6 protocol and be able to communicate with other devices over IPv6. Basic IPv6 support must be verified and certified by the IPv6 Ready program with a “Phase 1” logo certificate. A “Phase 2” logo certificate will be awarded additional points (+10%) in the tender evaluation procedure.

      Equipment that has not been put through the IPv6 Ready testing procedures must comply with the RFCs listed below:
