RE: auto rp ..ttl value ?

You lack clear knowledge that is in the CCIE Written study guide by Wendell Odom.

It has very specific details about what multicast message is sent to what group address and packet level details.

As a CCIE Candidate who has already passed the CCIE Written exam, you should now be preparing for your lab exam on live routers, running extensive debug's to create
a memory between what you learned in the book, the commands and the results.

This way you won't waste $3,000 in total lab fees and travel costs to sit the lab to realize you should have done this more BEFORE you lab date.

Get moving
