A year, or two, ago, I found such information buried within the Juniper website; however, upon recent attempts at further investigation, both for learning about certifications, and subject matter for this topic, I am unable to locate said information. The "historic Juniper" blurbs were very informative. I am sure that the information is still available, however, I have not been successful in locating it. As for the suggested avenues of investigation, I have not had any coding or employment experience at that level of router development so I don't have the level of specific knowledge-base to make such an inquiry about said reference tables. I also do not have $10-$20K or more to purchase a Juniper router box, so there would not much real motivation to answer my inquiries if I were to be able to get into contact with a sales rep with enough knowledge of the system code to have information to give me. I am very much making an initial inquiry in attempting to get that level of experience, hence my inquiry to the list. I am simply trying to make my own inquiries about the general case, so as to gain knowledge of what routes to take to gain said coding/development experience via experimentation, etc... (Please excuse the pun.) Thanks for the input, though.
