Question from IETF MBONED WG IEEE 802.1D-2004
GMRP implementation/deployment

• MBONED WG is in the process of writing a
  multicast routing architecture 1. One part of
  that is flooding reduction in LAN networks. The
  most typical solutions deployed include IGMP/MLD
  snooping, but IEEE 802.1D-2004 (and previous,
  separate specifications) also describe GARP
  Multicast Registration Protocol (GMRP) which
  could be used between a host and a switch to
  perform multicast flooding reduction.
• However, GMRP requires support at both the host
  stack and the switch. We know about at least one
  switch stack GMRP implementation, but it is not
  clear whether there is more widespread support.
  It is not clear whether host stacks support GMRP.
  
• The current MBONED WG document 1 states that
  GMRP "implementation status is unknown".

Question from IETF MBONED WG

• What does IEEE 802.1 think is the current status
  of LAN IP multicast flooding reduction?
• What does IEEE 802.1 see as the vision for LAN IP
  multicast flooding reduction?
• Deployment/implementation status?
• Could you summarize the implementation status of
  GMRP both at host and switch stacks?
• Could you summarize the deployment status of GMRP
  both at host and switch stacks?

IETF Interest in 802.1 CM

• transmission coexistence with
  congestion-controlled IP traffic
• potential for improvement but also for issues
• would like to suggest adding the following
  statement to the PAR

The working group will coordinate with the
Transport Area in the IETF on interactions with
congestion-controlled Internet traffic, such as
TCP, SCTP or DCCP.
