I have passed the CCIE SP Lab yesterday at Brussels. The results came in pretty fast aroung 10 PM. I will share my experience here. I will only share thinggs pertinating to the SP lab. There are many other posts abou the lab in general, preparations, what to expect, the proctors, etc.... Here we go:
- Don't forget to commit your changes
- Don't forget to create the BGP_PASS RPL to allow eBGP routes to pass
- Check each and every step on the way. You do not want to be troubleshooting CSC problem because one of your LDP session was not up.
- Logging is disabled on all the IOS devices with "no logging on / no logging console". I enable it but checked with the proctor who told me to make sure to put disabled it back at the end of my lab, which I did. Do not assume anything, you have a doubt, ask the proctor.
- Keep track of :
- BGP peerings (Route reflector for IPv4/IPv6 VPNv4/VPNv6)
- RPs per site
- MSDP Peerings
- Use the command 'ip route profile' to make sure that your routing is stable.
- There's a lot of reverse engineering in the lab. Many things are pre build for you with many many faults in IPv4 and IPv6 for all address families so know even worst get acquainted your protocols (BGP, OSPF, IS-IS,EIGRP, RIP, PIM) for both address families
- Verify all your neighboring as you go. OSPF, IS-IS, BGP, LDP, RSVP, PIM,etc… You do not want to troubleshooting OSPF neighboring because your MPLS TE is not working. You can waste a lot of time. Things build up as go. The further you go in the lab, the harder it will become to see small details.
- Besides the DOC-CD, Notepad is your next best friend. Many configurations are repetitive. You will gain time and reduce the chance of making a mistake by using it. I had 3 notepad widows one for TCL scripts, another one called "AT THE END" to put back the configurations I changed like logging, and another one for copy/paste configs to save time.
- Read the lab end to end before starting type. Everyword is important. The lab is pretty self explanatory but you have to know your stuff hence you need speed and accuracy.
- It's harder than the R&S lab but easier because to study because of less topic to focus on.
- Sent private emails to Brian and he helps out a lot. Even Mark Snow was available to meet me personally in Columbus, Ohio. How cool is that ?
- I was tested on all possible PE-CE Routing protocols, filtering and loop avoidance techniques.
- Use TCL scripts to check reachability for all address families. It's crutial. SP is all about reachability and doing the way they wanted it.
- Found 2 typos in the lab: OPSF instead of OSPF and PIM-SW instead of PIM-SM. I was kind enough to send a feedback :)
- during the end, my Internet Explorer froze. After killing the process in the Task Manager, I was not able to log back in the lab to display the tasks. I still had access to the devices. After multiple attemps with the proctor, we decided to save my configs and logg off. BY doing that, I lost all my TCL scripts and notepad notes. Lesson: do not open multiple IE windows even when going for the documentation.
- Request for reread after passing the lab ?????: You can request a reread even when you pass the lab. How stupid is that?????
- Now INE owes me 2 CCIE shirts :(
Do not hesitate if you have questions, I will help out as much as I can without breaking NDA of course ;)
