Creating an Implementation Plan and Documenting the Implementation


Implementing Routing in the NetworkAd-hoc approach Identify the need for the implementation Implement routing in the network

Structured approach Create an implementation plan Implement the solution Document the implementation


Structured ApproachWell-known models and methodologies that can aid in structuring the network implementation tasks include the following: Cisco Lifecycle Services (PPDIOO) IT Infrastructure Library (ITIL) Fault, Configuration, Accounting, Performance, and Security

(FCAPS) Telecommunications Management Network (TMN)

Choose a model with elements that fit your organization as well as its business and technical needs.


Models and Tools Select the implementation

model Adapt the model to your

organization’s needs Select the tools supporting

the model Create the implementation

plan


Create the Implementation Plan Identify the required information for the plan:

– Network-specific information, activities, and tasks– Dependencies of the existing installation– Recommended resources

Create the implementation plan Implement the solution Verify the implementation Create the documentation


Identify the Required Network Information Existing topology, equipment, and software version IP addressing plan Scalability configuration (summarization, stub areas, and so on) List of advertized networks Link utilization Metric requirements for primary and backup links


Site specific implementation requirements Dependencies on existing installation Configuration and verification commands Implementation schedule and resources Tools

Identify Other Requirements

Online Resources


Create the Implementation Plan Plan the work tasks Select the site-specific tools and configurations Configure and coordinate work with specialists Create verification tests


Implementation Plan Documentation Good documentation is a result of good processes and

procedures. Documentation must be:

– Correct – Up-to-date– Accessible

Documentation must support:– Future upgrades and changes– Troubleshooting– Reporting


What to Document? Network information Tools Resources Implementation plan tasks Verification tasks Performance measurement and results Screenshots and photos


Example: Implementation Plan Identify the existing situation and requirements Follow these steps to create an implementation plan:

– Plan– Select the tools and resources– Coordinate the work with specialists– Verify– Interpret the performance results– Document the baseline, performance, and recommendation


Enterprise Network Topology Required


Identify Network Information and Requirements Existing topology, equipment, and software version IP addressing plan, configuration, and link utilization Requirements for:

– Connectivity and configuration– Protection and optimization– Security and remote access


Creation of the Implementation Plan Create an implementation plan and document it

– Project contact list– Location information– Tasks and detailed descriptions– Verification steps– Representation of the results


Summary Using well known models and methodologies can aid in

structuring the network implementation tasks and creating an implementation plan.

An implementation plan consists of the project and network overview, required tools, and information, as well as the implementation tasks.

The tasks in the implementation plan provide a detailed explanation of all actions that must be taken in order to configure the network according to requirements.

Good documentation is a result of good processes and procedures, and includes performance testing and documentation of results.
