Just a small comment. MSDP / Anycast is becoming more and more popular in
enterprise networks as a preferred way of RP redundancy. Many people who
have centralized RP model use it this days, or thinking to migrate to it
from older AutoRP redundancy. AutoRP may still provide RP-group mapping,
especially when combined with scooping, but for redundancy Anycast becoming
the preferable choice.
Best regards,
Alexei

Well.... The way I would personally approach this is by just asking
yourself what could be accomplished with a limited number of routers and a
lot of other things to do? :)
You'll find that the answer could be MOST of that!
IMHO, MSDP is a service provier thing (along with Anycast). UDLR is
possible, but requires too many interfaces compared to other things you'll
want to do. Bidirectional PIM is possible but a more complicated scenario.
PGM is not likely other than a fluff thing since you won't have any clients
to test it anyway. SSM is plausible but an odd-ball thing.
With that all being said, I would be FAMILIAR with the topics. I would know
where they reside on the DocCD, but I would not spend a lot of time
stressing out about them.

Subject: Mcast on the Lab
I hate asking stupid questions along these lines since we all know that
anything is fair game in the CCIE lab, but would anyone like to elaborate on
which aspects of mcast I should study. Obviously items like PIM sparse and
dense mode as well as IGMP, Auto-rp and BSR should be known thoroughly, but
what about MSDP(Anycast RP), Bidirectional PIM, SSM, PGM, UDLR and so
on..... Obviously there are very few shortcuts when it some to studying for
this beast, but some topics definitely carry more weight then others, any
comments would be greatly appreciated!!! TIA, Jason
