Good Morning Ivan,

I would make sure you master all the topics on the blueprint.

Here is a resource to help you get started and for your better
understanding from the documentation website:

http://www.cisco.com/en/US/docs/ios-xml/ios/ipmulti/config_library/12-4t/imc-12-4t-library.html

My plan is to go through all the configuration guides for Multicast.
There is a lot of material to cover :)

Regards,
John
