NP level exam that covers multicast?

ehndeehnde Member Posts: 1,103
I've read that to bridge from CCNP level knowledge up to CCIE preparation one of the gaps in knowledge is multicast....but I need to learn multicast, as it is used extensively at work. Can anyone recommend a book on this topic? If there is a Cisco exam that covers this topic that would be even better.

I know it was in the BSCI exam but is not in the new ROUTE exam. Advice?

    The Odom CCIE R&S book has pretty good sections on multicast, otherwise, go buy this:

    Developing IP Multicast Networks, Volume I (paperback)

    The author is the guy who trains Cisco's people on multicast, so I'd say it's got a pretty good shot at being an authoritative text.

    icon_lol.gif I'll take the time to find out why multicast is so despicable, at least.

    That is more than I could have expected. I'll start with Odom's CCIE R&S and go from there. Thanks a ton!

    you could always pick up the lab portfolio's for the old CCNP curriculum. There were a few multicast labs in there. Its a good starting point.

    I think “very senior” gets stuck in there because the last six yahoos that applied for the position couldn’t tell a packet from a Snickers bar.

    I have not failed. I've just found 10,000 ways that won't work.

    out of curiousity, what is multicast used for at your work?

    I spend my days working with multicast and digital video, nothing despicable about it, it's fascinating. Everything is SSM and IGMP v3 these days, makes things simple not dealing with rendezvous points anymore.

    Unforutnately, Cisco still tests on the old stuff. I don't know what it is, but multicast is just a tough subject for me to wrap my brain around. Probably because I just don't work with it enough.

    Otoh, it's gotten a bit easier since I found out I can use iperf to generate multicast traffic. Beats the snot out of actually having to go install multicast applications so I can see it in action

    One thing I have noticed is that multicast is pretty elusive to a lot of engineers. Most don't seem to have a proper understanding of it and when forced to make it work will generally implement shoddy workarounds, i.e. applying static-group messages everywhere and rolling out dense-mode.

    The developing IP multicast networks book is very good.

    Doyle also covers it in Routing TCP/IP vol. 2

    It's covered somewhat in the SWITCH FLG book.

    I will have to check out iperf, I just always used VLC to stream traffic for my lab at home. You just have to be careful, it has a bug in the GUI that lets you set the TTL to whatever, but really it stays at 1. There is an easy work around though, I learned that lesson the hard way, after a couple days of configuring and reconfiguring I finally fired up wireshark to see what was going on. icon_smile.gif

    Same here, we take multicast video feeds from the national headends, studio feeds, satellite feeds and re-multiplex along with other processing and send it out to the hub sites to be converted to RF and sent out Fiber/Coax to the homes. Just get to understand the term RPF well, you have to think backwards alot.
