All things related to multicast

[Guy T Almes <>]

M'casters,

 I would also be interested in comments on Bill Nickless's note.
 SSM does seem to solve the wide-area source-discovery problem and let us 
avoid using or improving on MSDP.
 But I hope that Bill's issue (on the need to improve on our current habit 
of imposing on L2 switch vendors to snoop intelligently) will receive 
serious attention.
 So much of what makes the Internet powerful is the minimal constraints it 
imposes on L1/L2 protocols.  The result is often wonderful 
cost-effectiveness resulting from a nice variety of cheap fast robust L1/L2 
technologies with IP layered neatly on top.  The demands of multicast for 
snooping seem to go counter to that generally strong attribute of Internet 
engineering.

 Regards,
