前几日收到Cisco的邮件，通知CCIE R&S lab考试变体。“Upcoming revision to CCIE R&S Lab certification will become effective on October 18, 2009” 。新的版本是“CCIE R&S v4.0”，在2009年10月18日之前，老版CCIE R&S V3.0还可以继续使用。不过现在才开始备战CCIE R&S的朋友，直接准备V4版本吧。V3你是赶不及了。

官方的说法是:

Candidates who have exams scheduled October 18, 2009 or later should prepare using the CCIE R&S v4.0 Written Exam Topics (blueprints), CCIE R&S v4.0 Lab Exam Topics and the CCIE R&S v4.0 Lab Equipment and Software Versions.

我google了下，找到一个对官方这次CCIE R&S Lab变体总结的比较详细的站。引用了它的内容，仅为给备战CCIE R&S lab的朋友共享这份信息。如果需要看详细内容可以点击这里访问。

不用过多的解释CCIE是什么，CCIE怎么报考，CCIE怎么备战，CCIE能干什么之类的话题了。如果你不知道的话，请google。这里我只简单的说一下CCIE R&S v4.0的主要变化吧。

1.新增入了“Mobile CCIE Labs”, provide greater access to take your CCIE Routing & Switching Lab exam.

2.考试内容更新( Main changes): Larger Technology topics added: EIGRPv6, Optimized Edge Routing/Performance Routing, IPv6 multicast, MPLS VPN, RSVP.

3.新加入了—Troubleshooting. As of Oct 18th, the configuration section shrinks by 2 hours to 5.5 hours (appx), with a 2 hour troubleshooting section.

4.设备有变化—Version 3.0(effective through october 17.2009) / Version 4.0 (effective begining October 18, 2009)

Ladies and gentlemen, your new CCIE 4.0 lab! I fully expect to see all of the lab dates between now and 17 October to disappear pretty quickly as current candidates will make want to attempt the lab prior to the change-over date.

6.Lab Locations

In addition, Cisco has introduced Mobile CCIE Labs to provide greater access to Lab testing while greatly reducing travel time and expenses in regions without a Cisco CCIE lab location.

目前CCIE R&S v4.0的推出只针对CCIE R&S lab考试。同样的，mobile CCIE lab也是以CCIE R&S lab为试点推出。不知道这次的改革，对国内已经濒临混乱的CCIE人力市场会造成什么样的冲击，还是根本就和上次推出的“CCIE考试新增英文面试环节”一样，很快就被中国国情化了。我们拭目以待，同时也非常希望备战IT认证的朋友们能够理性的对待这些证书，理性的对待自己的能力，理性的对待中国的IT人力市场。
