Hi Guys! In my last blog post, we had a quick look at multicast and a more in depth look at how PIM  works, since this is a CCIE DC focused blog, and the Nexus 7000 uses PIM Sparse Mode, we spent most of our time looking at Sparse Mode and the way shared trees and shortest path trees work, including the shared tree to shortest path tree switchover.

Hi Guys!

As we all wait anxiously for the training vendors to release Rack Rentals (Come on guys! At least give us a FIRM date so we can plan appropriately!) I think it's a good idea to look at things you can study on the cheap that are going to end up in the exam.

One of those things is Multicast, the blueprint specifically mentions there will be multicast troubleshooting and I would bet bottom dollar it's to do with the OTV use of multicast, which means Nexus 7000, which Means PIM. We can test PIM in GNS, we can test PIM on our own home gear, OK the Syntax is not going to match between the platforms all the time, but the CONCEPTS will and CONCEPTS are what pass exams and lead to you being an expert!

The very best multicast book i have read thus far, and where i got most of the information for this blog post can be found at the end
