Cisco 360 CIERS1 - Review

This week i had the pleasure to take the CIERS1 course.
On the first day, i've done my first CCIE-like lab ever. The CIERS1-CA-LAB01.
My Score was 71/100 (Cisco states an average score on all attendants of 53/100)
So i think this was quite good for the first time.
Day 2-4 we had some lectures and smaller technology focussed labs (BGP,QoS,Multicast etc.)
But on the fifth day i made a momentous mistake, i didn't take the CIERS-CA-LAB02 guide to to the tasks. I  used the CIERS-CA-LAB01-guide. So i wasted 3,5 hours on doing CIERS-CA-LAB01 on a preconfigured network for the CIERS-CA-LAB02. I wondered about the wrong configured IPs, but didn't thought about it too long. I was just hunting for full IGP reachability. After 3 hours i had full IGP reachability and realized that i used the wrong lab guide. This made my day. I was so frustrated, that i didn't had passion to really start again.
I was very angry about myself. I did a write-erase-reload on every device and started again. But now with CIERS1-CA-LAB02-guide. My motivation was below -39843 and i only got 14 out of 75 point. I'm really pissed. I mean really really pissed.

So remind -> ALWAYS READ THE ENTIRE LAB BEFORE YOU START !!!!!!
 ALWAYS!!!!!!!!

The course consisted of 30 % lecture and 70 % labs.
- 1. Day - Assesment Lab (Frame Relay, Catalyst Configuration, IGP (OSPF,EIGRP,RIP), Reistribution,BGP)
- 2. Day - Review Assesment Lab and Technologys, Advanced BGP Lab (a bad next-hop issue)
- 3. Day - Review BGP, Review MPLS, Review Multicast, Multicast Lab
- 4. Day - Review QoS, QoS Lab, Troubleshooting Lab (CIERS-TA-LAB02 - 2 hours)
- 5. Day - Configuration Lab (CIERS-CA-LAB02 - 6 hours), Review Lab

My recommodations before go for the course :
- Master the Frame Relay-thing. I think younger network engineers (like me) don't understand Frame Relay at all, because they never ever used it. Frame-Relay is contained in every lab, i think. I will have to study on this section, especially the different ways of running OSPF over Frame Relay
- do a lot of small technology based-labs (master IGP) before you attend the course
- don't go there just after the written exam, the written exam is a piece of shit. Further study in every topic is necessary to get most out of CIERS1 (after this week, i have to admit that it was to early to attend this course)

Notes-Section : In OSPF, Loopbacks are always advertised as /32 except...

#Topology#

#Note#
In OSPF, Loopbacks are advertised as /32 as described in RFC2328 Section 9.1.
It is seemed as a stub host, because over a loopback, there will be no transit-traffic.

You can change this behavior with the ip ospf network point-to-point command on the Loopback-Interface. Have a look ->

Passed CCIE Writtem Exam v4.0

During the exam, at question 12-13 after hard multicast and Cisco IOS Firewall, i thought that could be hard. But as closer to the end, i had a good feeling :) and finally got ->

Score 921/1000


Had 77 questions. It was really mixed, every thing was asked. From QoS, over Multicast with MSDP, a few and very easy Spanning-Tree questions,easy BGP ones,hard Cisco IOS Firewall questions (never done this), Routing-Scenarios are doable. Almost everything from the blueprint mixed-up. In September 09 i tried the CCIE R&S 4.0 beta but failed. 80 % of the questions were about Spanning-Tree in CCIE v4 beta. Really though questions about BPDU packets and things like that. I was very frigthened for Spanning-Tree today, but the questions were CCNA-level ones.

What i used for preparation ->

- Routing TCP/IP Vol1 and Vol2 as refresher - the compendium
- MPLS VPN Architectures - Peplnjak - the best MPLS VPN book - learn MPLS VPN in a day
- Deploying IPv6 Networks - ISBN 1-58705-210-5 - the IPv6 book, not like the normal ones "IPv6 has a greater address space" i can't hear it anymore
- Internet Routing Architectures - Sam Halabi - (best BGP book)-(2nd Edition) (ISBN 9781578702336)

- Cisco Documnetation
- Work experience -> 8 years -> 3 years as CCNP -> 2 years as CCIP
- BCMSN,MCAST,BSCI,ONT,ISCW materials from Gl*b*l kno*l*dge

Review befor written exam
- CCIE Routing and Swichting Exam Certification Guide, Third Edition - ISBN-13: 978-1-58720-196-7
- CCIE Routing and Switching Written Exam Blueprint -> Cisco Documentations and Configuration Guides


Just a perfect day ...

Dumbass Mistakes (3) - No routes from one 6VPE to another 6VPE

#Topology#

#Symptom#
Die Routen von R1-CE war nur am R5-PE (vrf Customer), die R2-CE-Routen nur am R6-PE zu sehen.

#Resolution#
Beim zeichnen des Diagramms fällt es natürlich sofort auf, was hier schief geht. Einer der Sätze welche man in den Cisco-Büchern am häufigsten liest ->

"An autonomous system with internal BGP (IBGP) must have all of its IBGP peers connect to each other in a full mesh (where everyone speaks to everyone directly"

In der Beispielkonfig wurde eBGP Richtung Customer genutzt. Die CEs als Route-Reflector-client anzubinden wäre auch eine Lösung (funzt mit den c1841 - aber Achtung! Next-Hop anpassen)

6VPE - BGP PE-CE - Beispielkonfiguration

#Topology#

6VPE is possible with Cisco 1841 Routers (R4,R5,R6) with c1841-adventerprisek9-mz.124-24.T.bin
R1 and R2 are 2610XM

Redundanz-Test (disablen SW1 fa0/5)

Hier ist noch ein Trace-File vom PIMv2-Register/Register-Stop vom SW1 zum RP (R5), nachdem SW1 fa0/5 zum Redundanz-Test disabled wurde. Danach geht der Multicast-Flow ohne Encapsulation durch.
Damit der Traffic-Flow analog dem Schaubild läuft ist natürlich ein "ip pim spt-threshold infinite" notwendig, um den ShortestPathTree zu vermeiden.
