Mohammad Ali, CCIE #19811
khandan I have used INE work books Version 4 and I have rented racks from INE to practice in 2007.Finally I got my CCIE R&S on 14 january 2008. The workbooks were great. I think for Routing and Switching the INE workbooks are the best.Thanks a lot INE . . . I have bought INE workbooks (R&S, Security, Voice) with different INE account.
