Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

May include but not limited to large and small LANs, national WANs, the internet, VPNs, the use of the PSTN for dial-up modems only, private lines, data and voice.

Routing information protocol (RIP)
NetWare link state protocol (NLSP)
Open shortest-path first interior gateway protocol (OSPF)
Exterior gateway protocol and border gateway protocol (superseded by BGP).

May include but is not limited to how and what the organisation wants in regard to work environment, problem solution processes, preventative maintenance and diagnostic policy, roles and technical responsibilities in the IT department, vendor and product service-level support agreements

May be in reference to the business, system, application, network or people in the organisation

May include:
Transmission of IP datagrams over X.25, Frame Relay or ATM. (X.25 now superseded by such technologies as Frame Relay and Asynchronous Transfer Mode.)
Point to point protocol (PPP)
Synchronous data link control (SDLC)
Binary synchronous control (BSC)
High-level data link control (HDLC)
Advanced data communications protocol (ADCP)
Several of these may now be considered as legacy protocols, but, even though they may not be in current use, there is still a need to keep knowledge of the protocols for legacy installations.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Critical aspects of evidence
Assessment must confirm the ability to select and install a router using predetermined configuration and tests. Basic configuration capability is essential in demonstrating competency.

Knowledge and skills
Basic router commands
Router configuration, clock rate, routing protocol, password protection of router
Router-based network architectures
Effect of a router on delimiting broadcast traffic and on conserving bandwidth
Providing the network with redundant paths for reliability and the way routers manage these paths
How dynamic routing algorithms or protocols create and maintain routing tables
Use of routing tables in intelligent packet routing and switching
Router firewalls
Installing peripheral devices
Remote access skills using Telnet

Assessment guidance
The purpose of this unit is to define the standard of performance to be achieved in the workplace. In undertaking training and assessment activities related to this unit, consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs. Additional guidance on these and related matters is provided in ICA05 Section 1.
Competency in this unit should be assessed using summative assessment to ensure consistency of performance in a range of contexts. This unit can be assessed either in the workplace or in a simulated environment. However, simulated activities must closely reflect the workplace to enable full demonstration of competency.
The assessment of this unit of competency will usually include observation of router selection and configuration for a variety of scenarios
Assessment will usually include observation of real or simulated work processes and procedures and/or performance in a project context as well as questioning on underpinning knowledge and skills. The questioning of team members, supervisors, subordinates, peers and clients where appropriate may provide valuable input to the assessment process. The interdependence of units for assessment purposes may vary with the particular project or scenario.

In the case of this unit, it could be assessed in a holistic manner with:

ICAA4047B Determine project specifications and secure client agreement

Resources

To demonstrate competency in this unit the person will require access to:

Router specifications
Technical requirements for a network
Router
Cabling
Networked (LAN) computers
WAN service point of presence (or simulated)

Role context
A router connects networks together, controlling the routing of packets from source to destination and providing alternate paths when necessary. Routers are more sophisticated than bridges, connecting networks of different types and making logical routing decisions on the basis of available data. Typically a router hands off packets to another router along the path until the destination is reached.
In the context of the Internet, a router is a device or, in some cases, software in a computer, that directs information packets to the next point toward their destination. A router is located at any juncture of networks, including each Internet point-of-presence. As such, routers are key to the operation of the Internet.
It is essential that this unit covers a broad variety routers ranging from simple SOHO ADSL/CABLE routers, to complex fibre channel multi-routing units designed for backbone capability. Additionally, it is imperative that routers are provided for hands-on experience, particularly SOHO and Fibre channel routers.
The breadth, depth and complexity of knowledge and skills in this competency would cover a broad range of varied activities or application in a wider variety of contexts most of which are complex and non-routine. Leadership and guidance would be involved when organising activities of self and others as well as contributing to technical solutions of a non-routine or contingency nature.
Performance of a broad range of skilled applications including the requirement to evaluate and analyse current practices, develop new criteria and procedures for performing current practices and provision of some leadership and guidance to others in the application and planning of the skills would be characteristic.
Applications may involve responsibility for, and limited organisation of, others.

An individual demonstrating this competency would be able to:

Demonstrate understanding of a broad knowledge base incorporating some theoretical concepts
Apply solutions to a defined range of unpredictable problems
Identify and apply skill and knowledge areas to a wide variety of contexts, with depth in some areas
Identify, analyse and evaluate information from a variety of sources
Take responsibility for own outputs in relation to specified quality standards
Take limited responsibility for the quantity and quality of the output of others
Maintain knowledge of industry products and services
The scope and complexity of knowledge and skills is dependent on the tasks undertaken.

Additionally, an individual demonstrating this competency would be able to:

Configure and debug routers and routing tables
Select a router for a particular task
Interpret available information and request clarification where needed
Take responsibility for outputs in work and learning
