ISIS is still tested because people still use it to route IP. You won't see
ISIS routing CLNS on the exam, but it is still viable for IP and is
therefore still a test subject (particularly on the C&S, since a lot of
Service Providers swear by it).

Subject: Re: ISIS / OSPF Redistribution
about IS-IS, do you really think Cisco would pass up the chance to involve
another protocol in the lab? even if it was just for
redistribution/security?
