Hi Luis and Miguel
Thanks for the Webcast session, we learn a lot.
Please help to answer the questions that weren't covered during the alive session:
Do you recommend to use 239/8 or not to use it?
This this still the same issue if you have the 7Ks as your RP router?
When you mention 224.0.40? You mean Auto RP
Regarding if you should use 18.104.22.168/8, consider that segment is private, it's the analog for 10.0.0.0/8, meaning you have to use it in your organization.
Please consult Multicast Address ranges from IANA:
Regarding Nx7K, please share specific questions you may have.
Here's a brief guide to start with Multicast in NX7K.
And the configuration guide:
when I mention 22.214.171.124 I mean AutoRP discovery messages.
Those messages are sent by the RP Mapping agent to inform all PIM routers of available RP candidates in the network. Those candidates inform the mapping agent with RP announcement messages using 126.96.36.199 to share it's IP address and what groups they are working with as RP.
