Slow down, Bill. MAGMA is not specifying how L-2 devices behave.
The snooping draft is guidance to switch vendors who want to do
IGMP/MLD snooping. It is meant as an Informational document.
So why are the IETF working groups like MAGMA trying to guide Layer 2
switch multicast behavior?
Have you (or Ken) pushed on your router vendors to support this in
conjunction with the switch vendors?
I can say that there's some adoption by switch vendors:
Cisco Systems already supports GARP/GMRP. See, for example,
D-Link Systems claims future support for GARP/GMRP.
As of 2000 (at least), Cabletron/Enterasys supported GARP/GMRP.
Also, other areas of the IETF are aware of GARP/GMRP. For example, RFC
2878 (Standards Track) refers to GMRP support for the PPP Bridging Control
Protocol (BCP). http://www.ietf.org/rfc/rfc2878.txt
