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 congestioncontrolled 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.
