Re: Multicast stub routing...

If the task specifically mentioned Sparse-Dense, I would probably leave
that alone. No sense in losing points I already though I had! :)

The stub portion really doesn't have anything to do with specific sparse
or dense operations. It has to do with forwarding IGMP messages up
(offloading) and placing a filter on the upstream to make sure that it
expects that sort of behavior and doesn't have a full PIM relationship
as a normal interface would.

But yes, the command reference has little snippets of configurations
that are often helpful, particularly if someone in their infinite wisdom
decided to nuke a configuration guide page or four. :)
