Multicast Notes

From the Internet 2 Multicast Workshop held in Vancouver, May 1 2004.

Slides converted to PDF for easier viewing/searching (OpenOffice seems to have rotated some slides and lost some graphics, though...).
I added some Nortel commands to the troubleshooting guide.

Please see the Internet2.edu page for the original powerpoint slides, lab documents etc.
