  1. Hi All, I was wondering if I could get some clarification of the CCIE R&S lab exam conditions. I notice that a lot of the workbooks I have been working on have logging disabled (both console and buffered) and was wondering whether this was the default state of the lab kit? In assume it is ok to turn these on? I was also wondering whether the exam conditions/restrictions in the INE/IP Expert workbooks were indicative of the restrictions you would expect to see in the actual CCIE R&S lab? i.e. don't introduce static routing unless specified, use conventional routing protocols etc. Also, whilst I am posting... I have another question for those who have passed with regards to general lab approach. Do people read through the whole lab before starting, or through a whole section, or just go step by step? Also, if there are sections that are dependent on a subsequent section, do people leave this and come back to it, or configure the subsequent section as part of the question? For example, in a practice lab I am working on, OSPF is before the EIGRP and RIPv2 section, and in OSPF I have to redistribute a loopback interface as E2 (i.e. can't use network statement), but cannot use redistribute connected (i.e. have to redistribute via EIGRP or RIPv2) - would people leave this part of the question and come back to it in the end, or would they trawl through both the EIGRP and RIPv2 sections to figure out what they need to do to then be able to complete the OSPF requirement? A lot of questions I know... Thanks, goulin
  2. mpls traceroot

    Any Cisco IOS I tested on the CE in the 12.4(15)T range (from IP Base to Advanced Enterprise Services) seems to show the label information. As andr2ea_g mentioned, it depends on the IOS of the CE to disregard the ICMP extensions that the Cisco IOS on the PE sends. I've tried this with a Juniper MPLS core, and when I issue a traceroute from the CE, I don't see label information. So I think the issue is 2 fold - 1) The Cisco PE device is sending the ICMP extensions as per andr2ea_g link and 2) The Cisco IOSs (in particular, 12.4(15)T, but I am not sure from which IOS level/stream it started to do this) is displaying the ICMP extension information

    Thanks for the info. Based on your response, I guess the reason I am seeing MPLS info on CE1 is because of its IOS version/level. In answer to the earlier question, I want a traceroute from CE1 to CE2 to not show both the provider network (achieved through the no mpls ip propagate-ttl forwarded command) as well as the label information (which I am still seeing now)

    I tried adding this on all my P and PE routers, yet I still seem to get label information when I issue a traceroute from 1 CE to another: CE1.2691#traceroute Type escape sequence to abort. Tracing the route to 1 88 msec 76 msec 40 msec 2 [AS 1] [MPLS: Label 20 Exp 0] 136 msec 120 msec 168 msec 3 [AS 1] 256 msec 168 msec * Am I missing something else?
  5. CCIE R&S Written Material

    Thanks Darby. I've read yours (and some other blogs) regarding the way to approach the CCIE, and they've been really helpful. I do tend to agree with your approach... everyone I know has always approached it as 2 exams - written and lab, and prepared differently for both (i.e. cram for the exam, and practice labs for the lab). I think until I read the book and practice labs until I am comfortable and familiar with exactly how the technology works, how to configure and monitor/troubleshoot it, then there is no point in going for the written exam. My problem (and I am sure it is the same with a lot of other people) is that I don't have access to a personal lab to play around with. So I was going to go down the GNS3/Dynamips path for doing my labs for anything router related, and either by a 3560, or lease some rack time, to cover off the switching component (which I'd do last so that it was freshest in my mind before I did the exams). Hopefully that will be a successful path (since I am self funding the CCIE, I'd like to do it as cheap as possible so that I can pass within a reasonable timeframe and hopefully first go).
  6. NTP clock sync prob

    I assume that is your Lo0 address on R1? Have you tried running a debug on R1 and a client device? ntp clock-period <--- this comes automatically - from what I understand it indicates the difference between the time configured on the device vs the time on the internal clock of the device.
  7. CCIE R&S Written Material

    Hi, I am about to start to study for my CCIE Routing and Switching after 7 years working on Cisco hardware. My history... I have completed a CCNA/CCDA in 2005, CCNP/CCDP in 2006, CCIP in 2007, but haven't actively studied Routing and Switching material for a few years (other than passing the SRNS exam for re-certifying everything this year), but have worked in the networking field on Cisco hardware in all that time, mostly in network design. I was wondering what material people had used to pass the written exam? Would people say that the CCIE R & S Certification Guide 4th Edition contails adequate material to cover the requirements to pass the writen component? Or does this need to be supplimented with other material (for instance, when I sat the MPLS exam a few years ago, I used the Cisco course + a chapter from a really old book that covered the material in the exam - which funnily enough wasn't covered in the Cisco course)? Thanks, goulin
