1 Introduction

To ensure the smooth and cost-efficient uptake of IPv6 across their networks, it is important that large commercial, public sector or research and education governments and large enterprises specify requirements for IPv6 functionality and compatibility when drafting compatibility when seeking tenders for Information and Communication Technology (ICT) equipment and support.

This document is intended to provide a Best Current Practice (BCP) to support organisations in such tender processes, but and does not specify any standards or policy itself. It

is an update to ripe-554, which is the second version of the “Requirements for IPv6 in ICT Equipment” guidance.It offers guidance on what specifications to ask for and it is intended to be used

can serve as a template that can be used by governments, universities, large enterprises or any other organisation when specifying large enterprises and all other organisations when seeking IPv6 support in their tenders or equipment requirements. 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.

Be aware that the standards listed here have their origin in various bodies, principally the IETF, which operate independently which operate independent of the RIPE community, and that any of these standards might be changed or become replaced with a newer version. While this document has been approved by the RIPE membership, principally via the IPv6 WG, as of the date of publication, its contents will age as new RFCs or related documents are issued.

You may also need to adjust the recommendations to your specific local needs; again, this document is purely a template, and the suggested Mandatory and Optional elements may need to be tuned for your specific use case(s). needs.

Some parts of this section are loosely based on the NIST/USGv6 profile developed by the US government:

for which there is a newer version at:

The authors have modified the content of these documents to make them more universally applicable. This option includes a list of RFC specification standards, which standards that must be supported, divided into seven eight categories of devices. Note that this document removes the ‘mobile device’ category, instead including such devices as hosts.

This document also follows the IPv6 Node requirements document, RFC8504 (which updated RFC6434). This RFC contains RFC6434. This RFC is the general IETF guidance and consensus on what parts of IPv6 need to be implemented by different

devices, and its contents are generally reflected in this document.1.1 devices. General information on how to use this document

This document does not dictate specific technologies to be used, rather it assumes a network design/solution has been produced, and that design, and the components it uses, needs to be mapped to the procurement document. 

An IPv6 Ready Logo certificate can be required for hosts, routers, and CPE Routers. While the Logo certification was devised around 20 years ago, it is kept current with IPv6 standard updates and is a globally accepted program for vendors to promote their equipment and to assert that their equipment any device. This is the easiest way for vendors providing the equipment to prove that it fulfills basic IPv6 requirements. The IPv6 Ready Logo latest updates require that devices be tested in IPv6-only environments and have IPv6 enabled by default. 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 can't be accused of preferring any type or vendor of equipment.

For more information about the IPv6 Ready Logo program see: http://www.ipv6ready.org/ Link: http://www.ipv6ready.org/

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. Similarly, if features listed as Optional are required for the tender initiator’s specific use case(s), then those requirements should be made Mandatory. Please note that the tender initiator should decide what functionality is required, not the equipment

vendor; this document is simply a template. 1.2 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 the 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 *.

2 Proposed generic text for the tender initiator

In every tender, the following text shall be included:

All ICT hardware and software that is a as subject of this tender must support

the IPv6 protocol, and MUST operate in an IPv6-only environment. For example, where SNMP is used, it must be able to operate over IPv6 transport.If IPv4 is supported, similar performance and capabilities

both the IPv4 and IPv6 protocols. Similar performance must be provided for both protocols in input, output and/or throughput data-flow performance, transmission and processing of 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.

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

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

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

3 Categories of devices in scope for this document

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

Requirements are divided in 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, or for monitoring and accounting, throughput should also be required for IPv6 traffic.

3.1 Definitions and descriptions of different categories

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 (i.e., a Layer 2 switch can act as a layer-3 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.

Note that the mobile device category included in ripe-554 has been removed. Such devices now fall under the host category, such that they are considered only from their connectivity to the local infrastructure (via WiFi), and thus the 3GPP-related requirements are out of scope of this document.

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

This includes mobile devices attaching to local network infrastructure.

Host devices in an enterprise may be multihomed, mobile devices being one example, and devices with a network and management interface being another. The IETF has worked for many years on approaches to multihoming for IPv6. Specific [RFC4191] requirements are included in this document.

Switch, or ‘Layer-2 Switch’:

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

This category is further split below into consumer grade (typically for home use) and enterprise/ISP grade.

WiFi access points are technically not pure layer-2 devices, but they should (possibly in cooperation with a wireless controller) perform the same functionality as a layer-2 switch as far as IPv6 features are concerned. Thus the text from this section may also be used for WiFi access points.

Router or ‘Layer-3 Switch’:

Router or ‘Layer 3 Switch': A router or ‘layer-3 switch’ ‘Layer 3 switch' is a device that is primarily used for forwarding IP packets based on their attributes. Exchanging routing information with other routers 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 Layer 2 switch or a router/layer-3 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, Router, the requirements are different from an Enterprise/ISP

router/layer-3 switch. CPEs often need to support IPv6 transition mechanisms; this document will focus primarily on transition methods for IPv6-only networks.Load Balancer 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.

3.2 Things that are out of scope of this document

In the interests of reaching consensus to publish an update to ripe-554 as efficiently as possible, the authors minimised the addition of new types of devices.  These may be added in a future update, or as a separate update.

As stated above, mobile devices are considered in this document only in regards to their connectivity to the enterprise infrastructure (typically by WiFi) and in this respect are considered to be hosts.

Note that VMs and containers are out of scope for this document; these functions may be provided on systems procured as hosts via this guidance, but are not “ICT equipment” in themselves.

While [RFC8504] includes a section on YANG for network management, further YANG requirements are not included in this document.

Certain new routing functions that have emerged recently have also not been added at this point, one example being SRv6 [RFC8986].

4 Lists of required RFC RFC/3GPP standards for different categories types of hardware
ICT hardware equipment is divided in this document into seven functional groups:
  • Host: client
  • (including mobile device) or server
  • Consumer grade layer-2 switch
    • Enterprise/ISP grade layer-2 or serverLayer 2 switch
  • Router or layer-3 Layer 3 switch
  • Network security equipment (firewalls, IDS, IPS,...)
  • CPE equipment
  • Load Balancer
    • IPS...)
  • CPE
  • Mobile device
  • Load balancer

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

Any hardware that does not comply with all of the Mandatory mandatory standards 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 *.

    Requirements for "network security equipment”
    Equipment in this section is divided into three subgroups:
    • Firewall (FW)
    • Intrusion prevention device (IPS)
    • Application firewall (APFW)

    For every mandatory standard the applicable subgroups are specified in parentheses at the end of the line.

    Mandatory support:

    • ICMPv6 [RFC4443/STD89] [RFC4443] (FW, IPS, APFW) *
    • Transmission of IPv6 Packets over Ethernet Networks [RFC2464]
    • SLAAC [RFC4862] (FW, IPS) *
    • If support for SNMP is required:
      • SNMP protocol [RFC3411]
      • SNMP capabilities [RFC3412, RFC3413, RFC3414]
      • SNMP MIBs for IP [RFC4293] Forwarding [RFC4292] and DiffServ [RFC3289]
    • IPv6 Router Advertisement Options for DNS Configuration [RFC8106] (FW)

    • Neighbor Discovery [RFC4861] (FW, IPS, APFW) *
    • If the request is for the BGP4 protocol, the equipment must comply with RFC4271, RFC1772, RFC4760 and RFC2545 (FW, IPS, APFW)
    • If the request is for a dynamic internal gateway protocol (IGP), then the required RIPng [RFC2080], OSPFv3 OSPF-v3 [RFC5340] or IS-IS [RFC5308] must be supported. The contracting authority shall specify the required protocol. (FW, IPS, APFW)
    • If
    • OSPFv3 is requested, the equipment must comply with "Authentication/Confidentiality for OSPFv3" [RFC4552] or “Supporting Authentication Trailer for OSPFv3” [RFC7166] (FW, IPS, APFW)If OSPFv3 and SNMP are

    • Support for QoS [RFC2474, RFC3140] (FW, APFW)
    • If tunneling is required, the device must support Basic Transition Mechanisms for IPv6 Hosts and Routers [RFC4213] (FW)

    A Network Security Device is often placed where a layer-2 Layer 2 switch or a router/layer-3 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 functionality supported over IPv6. For example, if an intrusion prevention system is capable of operating over IPv4 in layer-2 and layer-3 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 synchronising IPv4 sessions between all members of a cluster, then this must also be possible with IPv6 sessions.

    5 (FW) Requirements for IPv6 support in software

    All software must support IPv4 and IPv6 and be able to communicate over IPv4-only, IPv6-only and dual-stack networks. If software includes network parameters in its local or remote server settings, it must should also support configuration of IPv6 parameters. All features that are offered over IPv4 must also be available over IPv6. The user should not experience any noticeable difference when software is communicating over IPv4 or IPv6, unless this is providing explicit benefit to the user.

    Software developer/vendor must at a minimum do the following things to guarantee this:

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

      [RFC6724]
    • Every place in the software where IP addresses are handled (such as in user interfaces, configuration parsing or where data is processed) all valid IPv6 address notations as specified in "IP Version 6 Addressing Architecture [RFC4291]" must be supported
    • Every place where IPv6 addresses are shown or output the notation as specified in "A Recommendation for IPv6 Address Text Representation [RFC5952]" should be followed
    • Resolving hostnames in DNS must support IPv6 (AAAA) answers
    • Connecting to other systems and receiving connections from other systems must support IPv6 connections using the appropriate system mechanisms (e.g. networking sockets)
    • When setting up a connection the software should follow Default Address Selection for Internet Protocol Version 6 [RFC6724] or Happy Eyeballs Version 2: Better Connectivity Using Concurrency [RFC8305]
    • These requirements should also be checked in any library or tools used by the software

      • This list is not exhaustive and only covers the basic requirements.

      The white paper "IP-version dependency in application software - Preparing source code for IPv6"[1] Link: #_ftn1 from the Netherlands IPv6 Foundation can be used to get developers started.

      6 IPsec: Mandatory vs Optional

      In the original IPv6 Node Requirements (RFC4294) IPsec was listed as a 'MUST' implement to be standards compliant. The updated Node Requirements RFC (RFC6434) published in 2011 changed IPsec to a 'SHOULD' implement. Reasons for the change were stated in that RFC.

      The RIPE IPv6 Working Group has extensively discussed whether to make IPsec support mandatory or optional.  When finalising ripe-554, the most vocal constituents showed support for moving IPsec to the optional sections, which is what is also reflected in this updated document.

      While the consensus of the community was to make IPsec optional in most cases, the IETF confirmed in 2019 in the latest version of the IPv6 Node Requirements standard (RFC8504) that IPsec 'SHOULD' be implemented (not ‘MUST’). 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, RFC8221, RFC7296 RFC7619 and RFC 8247] *

      The current set of mandatory-to-implement algorithms for the IPsec Architecture are defined in Cryptographic Algorithm Implementation Requirements for ESP and AH [RFC8221]. IPv6 nodes implementing the IPsec Architecture MUST conform to the requirements in [RFC8221].

      The current set of mandatory-to-implement algorithms for IKEv2 are defined in Cryptographic Algorithm Implementation Requirements for ESP and AH [RFC8247]. IPv6 nodes implementing IKEv2 MUST conform to the requirements in [RFC8247] and/or any future updates or replacements to [RFC8247].

      While the Authentication Header specified in RFC4302 was supposed to be the way to provide for integrity and non-repudiation, because it could not traverse NATs, it became common practice for ESP null to be used. As stated in Section 13.1 of RFC8504, which is taken from RFC4301, IPv6 nodes implementing the IPsec Architecture ‘MUST’ implement ESP (RFC4303) and ‘MAY’ implement AH (RFC4302).

    [RFC3484]. Skill requirements of the systems integrator

    Vendors and 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. Additionally these employees must These employees must also have general knowledge of the IPv6 protocol, IPv6 network planning and IPv6 security (eg. as indicated by (as also indicated by the certification for these skills also). skills). If it becomes obvious during the equipment installation and integration that the integrator’s 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 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.

    7.1 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

    equipment in the IPv6 ICT environment.Declaration IPv6 in the ICT environment.The declaration

    should say that the equipment supplier or system integrator declares under criminal and material responsibility:
    • That they have a sufficient number of people employed to perform the 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;
    • That the quality of offered services meets the requirements laid out in the tender documents, and that these requirements apply to both IPv4 and IPv6. 

    Note that declarations like this can vary depending on local legislation. Therefore translators and tender initiators should get legal advice on the exact wording for these requirements.
