Yes... If you're thinking what I'm thinking, IS-IS is covered in the CCNP, CCDP and CCIP certification (and recertification) exams. And these are definites in the exam (not maybes). http://www.cisco.com/warp/public/10/wwtraining/certprog/testing/current_ exams/642-801.html Hey look on the bright side - at least you don't have to learn about SNA for CCDP anymore. -----Original Message----- From: nznog [mailto:nznog(a)glassmile.co.nz] Sent: Thursday, 15 April 2004 22:07 To: nznog(a)list.waikato.ac.nz Subject: [nznog] Routing protocols What routing protocols do people use on their networks? Particularly inside. Does anyone in the world actually use IS-IS ? I am not interested in what network runs what, just how many networks run various protocols. Rough idea of network size would be nice, and any partcular reasons you prefer one to the other. thanks for satisfying my curiosity JM
