You'd have to turn on "pim" and "IGMP" on the interface that the hosts would
be connected to. Granted, you won't be able to ping if there is no static
"ip igmp join-group x.x.x.x" but if you had a PC you could test it by having
a host join. In scenarios like that, I would probably put a join-group on a
loopback and just make sure I could ping it.

I am doing an IPE lab that staes that R8 will be a multicast stub router and
has a source connected to it's Eth interface @ 224.88.88.88. However,
nowhere in the lab is a ip igmp join placed on any router. Without this,
would hosts be able to join that group. I know I will be unable to ping the
IP, but would this affect the hosts trying to join if no routers had 'igmp
join' for that group?
