All things related to multicast

[Alan Crosswell <>]

Does anybody know if there's a way to get link-layer IP multicast to do
the "right thing"?  I discovered that my link-layer multicasts were being
flooded by my Catalyst 4000 switch.  I think maybe this is just the way it
is since I would guess that by definition link-layer multicast doesn't ever
speak to the IGMP router.

I guess I will implement my subnet multicast with admin-scoped groups and
filters on my routers instead....

Comments, corrections, commissertaion? :-)
