I had a question regarding the JNCIP-ENT Exam Objectives. I see that Intermediate System to Intermediate System (IS-IS) is listed but I was just reviewing the contents of AJER (revision 11.a) and I don't see any material on IS-IS. Is this protocol still covered? I have other material I can use to brush up on IS-IS. I was just curious. I thought the AJER and AJEX course material where the only resources I would need to prep for the JNCIP-ENT.
