As most candidates preparing for the CCIE hopefully know by now, a blueprint change is coming for the CCIE R&S Lab in October 2009, which includes the new addition of MPLS. Tomorrow I will be teaching a free vSeminar entitled Introduction to MPLS for CCIE R&S Candidates at 11am PDT (GMT -8). Anyone interested is welcome to attend. Registration information is available at http://www.ine.com/free_ccie_vseminar.htm. If you are interested, but unable to attend, the session will be available in Class-on-Demand format shortly following its completion.

Class duration will be about two hours, and will focus on what will, and also importantly - what will not, be within the scope of MPLS topics for the new exam blueprint. Both theory and implementation will be covered. No previous knowledge of MPLS is required to attend.

Good luck in your continued preparation!

Hi, Everyone!

We are in the progress of upgrading our CCIE Security racks with the new software and hardware. Here are the specs that you can use to build your own rack. The rack consists of six routers, two switches, two ASA firewall appliances and one IPS sensor. The hardware models and their specs are outlined below:

R1-R5: 2611XM 32/128, IOS 12.4(15)T ADVANCED SECURITY
R6: 2811 64/256, IOS 12.4(24)T ADVANCED ENTERPRISE SERVICES
SW1-SW2: CAT3550, IOS 12.2(50)SEE
IPS: Cisco IPS 4235 or 4240, SW version 6.0(3)E1
ASA1-ASA2: Cisco ASA 5510, SW version 8.0
AAA/CA Server: Win 2k running CS ACS 4.0 and IPS Manager Express.
Test PC: Win XP workstation with ezVPN Client Installed.

You can find a more detailed topology description at IE's Security Hardware List

All the hardware cabling remains the same and the backbone routers did not change. If you compare this to our current hardware blueprint, you will see that only R6 needs to be replaced with an ISR router. Optionally, instead of 2811 you can use another ISR such as 1841 64/192 for R6. If you are using the Dynamips emulator for you virtual CCIE rack, you can use 3725 model for SSL VPN, for instance. Simply put, you just need any router that supports SSL VPN and other ADVANCED ENTERPRISE features. As for the GET VPN feature - even though Cisco FN does not list it as being supported by 2611XM routers, it is still present in the ADV. SECURITY feature set. Surprisingly enough, ADVANCED ENTERPRISE SERVICES image for 2611XM does not support the feature :)

Now for the IPS appliance: the latest software version for the IPS is 6.2 and it does not support older 4235 or 4215 IPS sensors (nor does version 6.1). Instead the blueprint suggests using the newer 4240 model. However, if you look at the release notes for IPS SW 6.2 and 6.1 you will note the following tow major new features:

a) IPS management via IPS Manager Express
b) IPv6 support

Other updates are minor, including some cosmetic changes such as health monitoring, customizable dashboards, uauthenticated NTP etc. Of course, you can still configure the IPS using IDM (IPS Device Manager) or the CLI and use IMX for appliance monitoring. As for IPv6, it is not the part of the current blueprint; plus the blueprint specifies IPS version 6.1 which does not support IPv6. Therefore, until they announced IPv6 as being testing in the CCIE Security blueprint, you may freely hang with the older IPS models and save on buying the more expensive 4240. Even better, the older 4215 appliance could be emulated on VMware! Note, that you will see the older 4235 models for some more time in our racks, but they are going to be gradually replaced with the newer 4240 models. The labs will still rely on the 6.0 code.

As for the switches - right now we use the 3550s in the racks, but those will be gradually replaced with 3560s. The CCIE hardware blueprint states the use of 3560 and 3750 switches in the lab. If you compare the 3560 model against 3550, you will see the following major differences: different QoS features, IPv6 support in the 3560 and no Private VLANs in the 3550 (even though the FN states they are supported there, sigh). Everything else is virtually the same. While QoS and IPv6 are not very important from the standpoint of the Security exam, Private VLANs are. However, if you look at the CCIE lab exam blueprint, you will see that Private VLANs are not listed there. Based on that, you can stick with the 3550s switches for 99% of the Security features tested in the CCIE lab.

Also, until April 20th you will see the PIX and the VPN3k appliances in our racks. So even if you are still pursuing the old-blueprint exam, you can use the rental racks, as most features are upwards compatible with the updated software. And get ready for the upcoming initial update of our IEWB-SC VOL1 next week – 50+ technology-focused scenarios for the ASA firewall appliance.

Good luck with your studies!

In this post we will give a brief overview of the upgrade path from CCIE Security v2.0 blueprint to v3.0. First off all, let’s start with the good news to everyone who was preparing using the old blueprint: most of things you have learned are incorporated smoothly in the new blueprint. Basically, the only thing to forget is your VPN3k configuration skills :) Everything else either remains the same or experiences an “incremental update”, like LAN-to-LAN VPNs with IPsec VTI interfaces. Let’s quickly review the changes made to the hardware and how they could potentially affect you.

  • Removal of the PIX and VPN3k devices, which is natural as both are EOL and EOS. Therefore, forget all about VPN3k menu system and enjoy the simpler topology without the PIX ;) However, to some people, getting a PIX is more affordable than getting an ASA. In this case, remember that the latest software release supported by the PIX is 8.0(4) (not the 8.1) and you cannot configure SSL VPN on PIX. Still, you can practice almost 90% of all the firewall features using the PIX.
  • Change from the Catalyst 3550 to 3560 models. From the security features standpoint, nothing has seriously changed. You can even continue using the older 3550 model, as they are probably cheaper to get nowadays.
  • The so much awaited upgrade from IOS 12.2T to IOS 12.4T. First of all, this might require a change in the hardware platforms you are using. If you were using non-ISR or non-2600XM routers, you will need to change the hardware platform to at least 2600XM with full flash/RAM memory (to run the Advanced Security feat. set) or the 1841 ISRs. Note that using Dynamips you can play with all 12.4T features without getting your hands around any real gear. Secondly, 12.4T introduces a ton of new features, as compared to the dusty 12.2T. However, it’s not that scary as it might look like. Most of the new security features relate to IOS PKI, some AAA enhancements, bunch of advanced VPN topics and infrastructure security. Probably, all the most notable features are VPN/Firewall related: IPsec VTI, WebVPN/SSL VPN support in IOS, DMVPN Phase3, GET VPN; Zone-Based and Transparent firewall, CBAC enhancements. Later in this document we will see those features detailed as the upgrade list of the new SC VOL1 labs.
  • ASA software upgrade from 7.x to 8.x. While is a major version jump, it does not imply the huger change in the CLI as it was with the upgrade from 6.x to 7.x. There is quite a bunch of new features in 8.x code (you will see the list later) but most of them are minor ones. Most likely you will enjoy things like Dynamic Access Policies, LDAP Authentication and Authorization, Secure Desktop Enhancements, EIGRP Support (who needs that?:), Transparent Firewall NAT and Traffic Shaping. However, if you are solid with the code version 7.x you wont face big problems mastering the new topics.
  • IPS software upgrade from 5.1 to 6.1 and the platform change to 4240. The catch here is that IPS v6.1 does not support many older IDS/IPS appliances, such as 4215 or 4235 and getting a 4240 might be expensive. However, there is some good news still. The CLI has not changed as much as it did with the 4.x to 5.1 upgrade, and all your 5.1 knowledge remains valid and up to date. The most notable new features are Virtual Sensors, Anomaly Detection, Threat Rating and the new IPS Manager Express. If you are OK with doing all your configurations via CLI, you can stick with IPS v6.0 which you could run on the older platforms (4215, 4235) as there are just minor differences between 6.0 and 6.1 (mostly related to IPS Manager Express). Probably the best news is that the old 4215 platform could be successfully emulated in VMware.

Now, let’s look at the v2.0 to v3.0 upgrade path that you can take with out products. Below is the list of the VOL1 technology labs. You can see the outdated topics being deleted and the new topics (which are being developed) highlighted. Naturally, many older labs remain perfectly valid for the new track, and you can continue practicing them while waiting for the upgrade being released. We also decided to keep the NAC labs, even though NAC is not on the current blueprint, mostly because it gives you a perfect scenario for advanced ACS configuration. Of course, if you own our current v2.0 products, you will receive the v3.0 updates free of charge.

The VOL2 upgrade will be taking place in parallel with VOL1 updates. What you should expect is removal of the VPN3k and (probably) PIX and the changes to the approximately 30% of the material. Many of the existing v2.0 tasks will remain the same, so you can practice the existing material, ignoring anything related to VPN3k (but not the PIX, as many of the PIX features remain unmodified in the new blueprint).

Good luck with your studies!

In this post I will try to summarize the things known so far about the CCDE written/practical exams and provide some (hopefully) useful tips and hint. Even though I didn’t receive my exam results yet, I think it’s still a good idea. At least, I’m still the person who “tried” and haven’t “failed” yet (at least unaware of that :)

The first question that people ask – would getting CCDA and CCDP help in achieving CCDE? That would help, a little. Most useful thing would be summarization your knowledge of IP Routing protocols and QoS topics. Plus, you can find some useful things in the new ARCH2 training course. However, I don’t think it is necessary to become a CCDP in order to get enough knowledge for taking CCDE.

Written Test

This one looks remarkably close to any CCIE written test you have taken before. You have about 100 questions to be answered in 2 hours following this *very* detailed blueprint:

CCDE Written Exam Blueprint

Look at the top-level sections of the document:

IP Routing. This is the section you should pay most of your attention to. You must know everything about OSPF, ISIS, EIGRP and BGP. Specifically, you should learn anything related to protocol deployment and scalability issues – things like summarization, flooding domain, route filtering, BGP topologies, traffic engineering. The exam contains a lot of “scenario-type” questions, providing information on a particular topology and configuration and asking questions that require some basic analysis. Don’t expect to encounter questions like “which command tunes OSPF LSA throttling” but expect things like “where would you place flooding domain boundary” or “what would you do reduce the impact of a flapping link”. There is no single book to cover all the section topics in depth, but here is a list that I would recommend:

Jeff’s Doyle “Routing TCP/IP Vol 1,2” and R. Zhang, M. Bartell “BGP Design and Implementation”

Additionally, look through the relevant tech notes for all protocols here:

Routing Protocols Support Page

When you’re done with in-depth reading on protocols, read the following “final” book: R. White, A. Retana, D. Slice “Optimal Routing Design”. This book covers the design topics in quite generic manner. For the “IP Routing” section focus on the chapters dedicated to routing protocols only. At first sight, the book might look a little bit boring, as it does not focus on gory details, but goes over talking about “generic” topics. Remember, knowing “IP Routing” in-depth is about 60% of your success in the written test.

Tunneling. What they mean by that are various “virtualization” techniques. This includes L3 and L2 tunneling techniques, most notably using MPLS and classic IP packet technologies such as GRE, mGRE, L2TPv3. This is where they are going to test your knowledge of L3 and L2 VPNs (e.g. VPLS), MPLS FRR and other VPN topics. This section is probably the next largest in the exam, constituting about 20-30% of the content that you should absorb. Here is a recommended reading list. First, if you’re not well familiar with MPLS, read the following as a good intro:

I. Pepelnjak, J. Guichard “MPLS and VPN Architectures”, a good additional books is J. Guichard, et. Al “Definitive MPLS Network Designs”.

Other books for this section:

W. Luo, et. al “Layer 2 VPN Architectures” and E. Osborne, A. Simha “Traffic Engineering with MPLS”

Also you may look through the section of “Optimal Routing Design” dedicated to the tunneling technologies for a brief summary. Don’t expect the exam to ask you in-depth technology questions like “what is the meaning of this bit in AToM control word”. Most likely you’ll be asked to pick up the best technology for implementing a particular solution (like what is the best VPN solution to transport multicast securely over SP core given the following limitations, etc).

QoS. This is the topic that most people hate :) With respect to the CCDE exam you are not required to know all the flavors of FRTS. Rather, what you should know are theoretical aspects of QoS implementation, such as QoS models (e.g. Diff/Int Serv) and mapping of application performance requirements to a particular QoS technology (e.g. policing or LLQ). You are expected to know the generic requirements of different application types (e.g. video, interactive traffic) with respect to network characteristics and understand the performance impact caused by QoS implementations. Of course, you need to know all QoS technologies available on Cisco routers as well (classification, marking, conditioning, policing, congestion management and avoidance). Most notably, you need to know how QoS applies in “virtualized” or “tunneled” environments, such as MPLS VPNs (e.g. pipe, short-pipe and uniform QoS models). The blueprint provides A LOT of details for QoS section. Don’t be scared, though. Most of the topics are just analytical breakdown of generic QoS models such as DiffServ. And besides, QoS does not constitute the huge part of the written test. What I would recommend to read on the QoS topics is the following list:

S. Vegesna “IP Quality Of Service” and probably S. Alvarez “QoS for IP/MPLS Networks”

Remember, QoS topics might look overly complicated at first sight. Make sure you master the fundamental concepts of QoS models and understand the implication of QoS configurations on application performance. They wont ask you crazy questions like 10xG.729 cRTP calls bandwidth consumption, but may ask things like “what technology should be used to provide differentiated services for applications sharing the same MPLS LSP”.

Management. This one should be relatively easy, as they wont ask you questions about Cisco Works or Tivoli :) Most likely you need to demonstrate the knowledge of show and debug commands as well as various system monitoring technologies, such as syslog, netflow, RMON, SNMP etc. You may want to take a quick look over A. Clemm’s “Network Management” book, but you probably should better focus at the IOS DocCD section dedicated to “IP Services” and “Network Management” commands and features. Don’t get stuck with in-depth theory of network management, like you would do with QoS. You may expect questions like “choose an optimal technology to extract particular type of information from traffic flows” etc.

Security. You need to know a little about generic concepts such risk analysis, security policy, policy enforcement, role separations, intrusion detection, event correlation etc. However, the top priority for you with this section is studying IOS security features and tools. This includes AAA, packet filtering, firewall features, routing protocol security, and infrastructure protection. Also, make sure you understand some advanced topics such as RTBH and sink-holes, which are related to SP security toolkit. In general, this section does not require detailed knowledge of all security features, but you’d better look under the “Security” section of the DocCD to have basic understanding of all IOS security features.

To summarize, I think you need to focus on the top three sections: Routing, Tunneling, QoS and spend less time on Management and Security. Of course that does not mean you can simply ignore those two “outsiders”, but rather gives you an idea of how to plan your study time.

Practical Test

First of all, you may want to read some of our previous blog posts on the CCDE practical exam.

CCDE Practical Perspectives

and

The general feeling of the CCDE Practical

The “practical” test itself does not involve any real hardware configuration. The exam is built using Adobe Flash engine. There are few sections, with every section build around a particular network topology (the same topology diagrams) you are supposed to work with. For every topology you are given a number of scenarios (approximately 30-35 questions each), that require the following, per the exam blueprint:

Gather, clarify, and analyze existing and new network requirements

  • Identify requirements and determine how they shape the purpose and expectations of a given network.
  • Demonstrate the ability to gather and validate information about an existing network.

This one is tough, even though it’s mostly reading. In the beginning of every scenario they give you the diagrams and an initial set of documents describing the current network design. Those documents contain quite a lot of information, with some part being more or less relevant to your scenario. What you need to do is perform an analysis, extracting the key concept, business and technical requirements and constrains (sounds easy, huh). For a non-native English speaker this is more time-consuming, since the information could be presented in “free-formats” such as emails or minutes and require additional “processing”. The engine will then ask you some questions testing your ability to extract the key concepts and find the correct questions to ask from the customer. As you could see from the “demo” test, you are offered to request additional information on the network. Whether you selected the correct or wrong choices, the engine presents you the “correct” information. The final result of this section is set of documents that provide all the relevant information you need to complete the particular scenario. The format of the documents could be different, but most of the time it includes some “live” conversations reflecting the real-life work flow.

Develop network designs to meet functional specifications

  • Choose the correct technology to resolve a specific network design problem.
  • Create a network design that minimizes or eliminates negative impact on the existing network and services.
  • Create a network design that is scalable.
  • Create a network design that is elegant and supportable.
  • Create a network design that is resilient.

This part follows the information gathering. Now the engine asks you some questions on relevant technologies. You may need to clarify your choices, as the engine may ask for justification of your selections. The funniest part is the ability to work with network diagrams. The Flash engine allows you enhancing the existing diagrams, placing additional devices (routers, switches) or links (e.g. physical connections or tunnels) and choosing the functional role of devices in the network. The design you are creating should satisfy the scalability and resiliency requirements stated above. You can try working with the diagram using the demo test. Again, even if you provide an incorrect solution, the engine will give you the “correct” design when the next part of the scenario will start. So you can always see how far from the successful design you have been :)

Develop a plan to implement network design changes

  • Evaluate the impact of implementation options.
  • Develop contingency plans for network restoration.

This section is relatively short. The engine asks you to arrange the network changes in the optimal order. You can see that in the demo test as well. The order you choose should provide less impact on the existing topology and should be logically consistent, e.g. you cannot deploy L3 before you enable MPLS in the core. However, it is not all that simple. Sometimes it makes almost no difference to place a particular step before or after another one. Most likely this means you miss something important ;)

Convey design decisions and rationale

  • Justify network design choices based on functional specifications.
  • Justify technology choices based on technical requirements

This may happen at any point within the exam where you are asked to select a particular technology or solution. The engine may ask you to justify your choice and provide rational arguments behind your selection. Even though you may have selected an incorrect choice, it still has some rationale options that you may select from.

Practical Exam Summary

The exam is very exhausting. Like I mentioned, first four hours could draw all your motivation off. So make sure you have enough strength to read a lot of documents and grasp tons of diagrams :) The problem is the exam stress, which may affect your ability to concentrate and understand information presented. During the exam, try taking short breaks and relaxing, as you may feel your brain burning out due to exception load of new information (at least this is what I felt afte 5 hours :)

As for the preparation, there is no special reading list that I would recommend. Theoretical concepts that you need are contained within the books recommended for the written test. You don’t have to practice any lab equipment, as with the CCIE exam, you just need to develop you analytical skills and patience :) Compared to the CCIE lab exam the CCDE practical might look “unfair”. After all, during the lab exam you have full control of the situation. Unlike this, during the CCDE practical the engine controls all your actions, and sometimes you may find that even though your answers might constitute a valid solution, the engine suddenly cuts your line of deduction and throws the “valid” solution on the screen. Sometimes you don’t even have chance to justify your selection, as the engine seems to mark it as incorrect immediately. This lack of options might be frustrating to many and a panel board review could constitute a truly fair examination. However, remember that there are people who already passed the CCDE test, and therefore you have a real chance :)

Hi gang. If you are a "tweener" like me as you are looking at this lab track, I thought you might like a list of the topics in the new blueprint that do not exist in the old. Also, notice that many topics that exist in both are being implemented on different equipment. For example, in the old you might do an SSL VPN on the concentrator, but now you would be limited to IOS or ASA.

Section II Cisco IOS Firewalls

B. Zone-Based Firewalls

Section III VPN

D. Group Encrypted Transport (GET) VPN
J. AnyConnect VPN

Section IV IPS

D. Virtual Sensors
E. Security Policies

Section V Identity Management

B. LDAP

Section VI Control Plane/Management Plan Security

A. Implement routing plane security features (protocol authentication, route filtering)
B. Configure Control Plane Policing
C. Configure CP protection and management protection
D. Configure broadcast control and switchport security
E. Configure additional CPU protection mechanisms (options drop, logging interval)
F. Disable unnecessary services
G. Control device access (Telnet, HTTP, SSH, Privilege levels)
H. Configure SNMP, Syslog, AAA, NTP
I. Configure service authentication (FTP, Telnet, HTTP, other)
J. Configure RADIUS and TACACS+ security protocols
K. Configure device management and security

Section VIII Network Attacks

B. Malicious IP Option Usage
