Perspectives on Design• Basic design is no longer widely taught or practiced

- It just works - It’s easy

- It’s not exciting, it’s just plumbing - It’s not new

• And yet...

Basic design problems still crop up

“Exciting stuff” doesn’t work without a solid routed design

We spend far too much time and money managing failures in basic design work

Jawdat 2012 2020

Perspectives on Design• Create a certification relevant to designers

• Provide a baseline set of skills

Builds on top of these skills, not in lieu of them

Encourages picking up “skipped skills”

• Encourage end-to-end (big picture) design thinking

Places in the Network are great, within the framework of a running network

Technologies are great, but need to be used for larger design goals

Jawdat 2012 2121

Perspectives on Design• Interact horizontally with middle level

business management

• Understand impact of business decisions and direction on design

Jawdat 2012 22

Design Certification• Where is this network now?

• What changes do I need to make to....

Merge these networks?

Implement this application?

Provide security?

Prepare for the next five years?

CCDE Practical Exam 2014

Jawdat 2012 3535

CCDE Practical• To take exam, candidate must:

Pass CCDE Written

CCDE Written exam attempt must be valid

• How to Keep CCDE Written ValidInitial attempt of CCDE Practical must be within 18 months of passing CCDE writtenCandidates who do not pass CCDE Practical must re-attempt CCDE Practical within 12 months of last scored attemptCandidates who do not pass CCDE Practical within three years of passing CCDE Written must retake the CCDE Written before being allowed to re-attempt CCDE Practical

• To maintain active CCDE status, CCDEs are required to pass expert-level certification exam every 24 months

After 24 months, CCDE is suspended.

Suspended candidates have one year to recertify with CCDE Written else all requirements must be completed again

Jawdat 2012 3636

CCDE Practical Exam Scoring• Unlike CCIE, there is partial score in CCDE

• Exam results scored after each administration; Candidates receive results PASS or FAIL immediately at the end of exam!

It seems like now it’s only automated grading using scoring rubrics and statistical analysis (no manual grading)

Some items are worth multiple points, with partial scoring

Some items have multiple solutions

Must achieve minimum score to pass

• Once you pass, it may take several days to get your CCDE number

CCDE Blueprints and Candidate Mindsets

Jawdat 2012 4242

Blueprints• CCDE Blueprints:

represent important high-level design-specific topics

assessed by CCDE Written and CCDE Practical exams

• Exam questions are aligned to blueprints in order to assess candidates’ expert-level design-related skills, knowledge, and abilities

Jawdat 2012 43

"CCDE Practical is multidimensional, each question or problem must map to all three blueprints"

TECCCDE-8005

Jawdat 2012 4444

The Three Blueprints• Task Domains

• Job Tasks

• Technologies

Jawdat 2012 4545

Task Domains• Merge/Divest

• Add Technology

• Replace Technology

• Scaling

Jawdat 2012 4646

Job Tasks• Analyze

• Design

• Implement & Deploy

• Validate & Optimize

Jawdat 2012 4747

A Word on CCDE Technologies• Essentially…

Any published RFC implemented by more than one vendor

Any common industry technology

Any common industry practice

EIGRP (may see LISP, OTV, DMVPN too)

• You do not “go forth and configure”

This is higher level than the “?”

• This is not about choosing the right equipment in the right place

Hardware limitations only come in at a high level

Jawdat 2012 4848

Jawdat 2012 4949

Business Drivers• How rapidly does the business

change?

• What is the business sizing model (growth/downsize/steady)?

• What are the key business processes?

• What is the business’ attitudes towards the network?

Jawdat 2012 5050

Application Drivers• What are the key applications on the

network?

• What are the characteristics of this set of applications?

Bandwidth requirements?

Tolerance for delay?

Tolerance for jitter?

Tolerance of network reconvergence?

Jawdat 2012 5151

Link Drivers• What’s the bandwidth?

• What’s the delay profile?

• What’s the jitter profile?

• How fast does layer 3 learn about a failure?

Jawdat 2012 5252

Where it all Meets• All of these drivers meet at layer 3,

the control plane

This is why the CCDE is a control plane driven test

If you can’t do layer 3, you can’t build a network that will support business requirements and applications on top of available links and hardware

• The control plane provides the tools to bring layer 9, layer 7, and layer 1 together

Jawdat 2012 53

CCDE Written Sample Questions

Jawdat 2012 5454

Routing Examples• Why would you configure A as ABR?

To reduce Router B’s routing table size

To reduce the complexity of the full mesh

To reduce the impact of Router B failing at Router C

To reduce the total time required to run SPF at Router A

ABR?

Jawdat 2012 5555

Tunneling Examples• When using any form of IPSec over GRE tunneling (for instance, DMVPNs) over a

public or private network, how many routing instances will you need to provide full reachability?

One

Two

Three

Four

Jawdat 2012 5656

Quality of Service Examples• Which would you deploy to increase the throughput of multiple TCP traffic flows on a

single link?

Head of queue dropping

Traffic Policing

Weighted RED

Traffic Shaping

Jawdat 2012 57

CCDE Practical Sample Question

Jawdat 2012 5858

Background: Business Information• A single network infrastructure to lower cost

Jawdat 2012 59

Background: SLA Information

• Privacy protection for customers

• No client-to-client leakage

Routing separation

Traffic separation

• Resilience and fast convergence

Jawdat 2012 6060

Background: Internal Standards• Traffic must pass

through a firewall between the client and the data center

• Client routes carried in BGP, not in local IGP

• Traffic carried outside the LISP network will be carried in SSL or IPsec

Jawdat 2012 6161

Background

IPsec tunnel termination

Jawdat 2012 6262

The Problem• Holey Doughnuts has done a security audit

• Their auditors discovered they can reach servers not belonging to Holey Doughnuts!

They specifically mention being able to reach the servers used by SuperExcel

They note there are routes they don’t recognize on their CE

Jawdat 2012 6363

Item 1 Root Question• Is Holey Doughnut’s ability to see routes

from SuperExcel, and reach SuperExcel’s servers, a problem that needs to be addressed by LISP?

Yes

No

Jawdat 2012 6464

Item 1 Root Explained

The answer is yes

Jawdat 2012 6565

Item 1 “No” Branch• This Is Not a Problem LISP Needs to Solve

• Why don’t you think this is a problem that needs to be addressed by LISP?

Holy Doughnut’s engineers cannot get to SuperExcel’s data, so this is not a breach of the SLA

Holy Doughnuts should address this by reconfiguring their route and packet filters

The LISP Service Level Agreement with Holy Doughnuts does not cover this situation

The LISP engineering team has bigger things to worry about than this problem

Jawdat 2012 6666

Item 1 “No” Branch Explained• This Is Not a Problem LISP Needs to Solve

• Why don’t you think this is a problem that needs to be addressed by LISP?

Holy Doughnut’s engineers cannot get to SuperExcel’s data, so this is not a breach of the SLA

Holy Doughnuts should address this by reconfiguring their route and packet filters

The LISP Service Level Agreement with Holy Doughnuts does not cover this situation

The LISP engineering team has bigger things to worry about than this problem

Jawdat 2012 6767

Item 1 “Yes” Branch• This Is a Problem LISP Needs to Solve

• Why do you think this problem needs to be addressed by LISP?

LISP should not be leaking the SuperExcel routes to their other clients

LISP should not be allowing telnet traffic from Holey Donuts to SuperExcel’s servers

LISP is not fulfilling their service level agreement correctly

Jawdat 2012 6868

Item 1 “Yes” Branch Explained• This Is a Problem LISP Needs to Solve

• Why do you think this problem needs to be addressed by LISP?

LISP should not be leaking the SuperExcel routes to their other clients

LISP should not be allowing telnet traffic from Holey Donuts to SuperExcel’s servers

LISP is not fulfilling their service level agreement correctly

Jawdat 2012 6969

Item 3• Which solution would resolve this problem in a way that supports both the SLA and the

LISP business model?

Using Policy Based Routing to separate customer traffic

Creating a physical per customer to separate customer traffic

Provisioning a separate virtual topology per customer

Configuring a separate IGP instance per customer to separate customer routes

Jawdat 2012 7070

Item 3 Answer• Which solution would resolve this problem in a way that supports both the SLA and the

LISP business model?

Using Policy Based Routing to separate customer traffic

Creating a physical per customer to separate customer traffic

Provisioning a separate virtual topology per customer

Configuring a separate IGP instance per customer to separate customer routes

We need traffic separation as well a routing separation

Jawdat 2012 7171

Item 3 Answer Explained• A single network infrastructure to lower cost

Jawdat 2012 7272

Item 4• What additional piece of information would you need to determine which virtualization

service you would use to separate customer traffic in this network?

The tunneling technologies the firewalls support

The tunneling technologies the call managers support

Tunneling technology used to connect to customer CEs

Jawdat 2012 7373

Item 4 Requirements• From time to time during the test, you will be asked what further information you need to

complete the task

• If you already have a specific piece of information, don’t ask for it!

This might not match “real life” as well as you’d like

But the question is trying to evaluate whether or not you know the information you need to solve the problem

• This is one of the analytical skills the test is designed to measure
