Yes, I beleive that static-rp works just fine. Just wanted to make the lab
harder then it was.... 5 days and counting.....

use a static rp-address if you have to run sparse only. Ronnie made an
excellent point about auto-rp and it not working in sparse-only. You can
see this if you look at the (*,G) output for 224.0.1.40, you'll see the
"D" flag for dense mode. You should run sparse-dense when using auto-rp
or use static rp addresses if just using sparse mode.
