IGMPv3 and MLDv2 Update Survey
draft-eckert-pim-igmp-mld-questionnaire-02
Abstract
The PIM WG intends to progress IGMPv3 and MLDv2 from Proposed
Standards to Internet Standards. This document describes the
motivation, procedures and questions proposed for a survey of
operators, vendors and implementors of IGMPv3 and MLDv2. The
objective of the survey is to collate information to help the PIM WG
progress these protocols to Internet Standards.

1. Introduction
Internet Group Management Protocol Version 3 (IGMPv3) [RFC3376] and
Multicast Listener Discovery Version 2 (MLDv2) for IPv6 [RFC3810] are
currently Proposed Standards. Given the fact that multiple
independent implementations of these protocols exist and they have
been successfully and widely used operationally, the PIM WG is keen
to progress these protocols to Internet Standards. In order to
facilitate this effort, it is critical to establish if there are
features specified in [RFC3376] and [RFC3810] that have not been

Internet-Draft IGMPv3 and MLDv2 Update Survey November 2019
widely used and also to determine any interoperability issues that
have arisen from using the protocols.
Following approach taken for PIM-SM, documented in [RFC7063], the PIM
WG has decided that conducting a comprehensive survey on
implementations and deployment of IGMPv3 and MLDv2 will provide
valuable information to facilitate their progression to Internet
Standard.
This document describes the procedures proposed for conducting the
survey and introduces the proposed questions.
2. Procedures Followed
2.1. Methodology
The PIM WG Chairs will officially kick off the survey and distribute
the questionnaire and pertinent information through appropriate
forums, aiming to ensure the survey reaches as wide an audience as
possible.
An online survey tool will be used in order make the submission and
processing of returns as convenient as possible. Therefore, the
questions proposed in this document will be transcribed to the online
tool and the URL distributed to potential survey participants.
2.2. Intended Recipients of Questionnaire
1. Network operators
2. Router vendors
3. Switch vendors
4. Host implementors
2.3. Processing of Responses
The submitted responses will be collected by a neutral third-party
and kept strictly confidential. The published results will be
anonymized and so the contributions by individual operators, vendors
or implementors will not be identified. Therefore, survey responders
will be identified but they would not be associated with a specific
response. Furthermore, there is an option to complete the
questionnaire anonymously, in which case the responder will not be
identified in the report.

Tim Chown has kindly agreed to anonymize the responses to this
questionnaire. Tim has considerable multicast expertise but has no
direct financial interest in this matter nor ties to any of the
vendors involved. Tim works at Jisc, who run the UK's national
research and education network, Janet, and has been active in the
IETF for many years.
