Hi,

I was responding to the original claim that "PPP does not support PIM".

Well, it does.

Of course there might be other ways to get multicast streams across a PPP
link - but the original posting didn't even mention "dialup" or
"terminal servers".  There's more PPP than "end users".

(But *if* you connect end users using PPP, you don't need an IGMP proxy
on the ISP side - either the end user is directly connecting his machine
to the PPP link, in which case it's "direct IGMP, no proxy", or the 
end user has a router, in which case the IGMP proxy needs to be on the
CPE, not on the dialup/terminal server).
