Scenario
ABC Pte Ltd is a one-stop provider of IT solutions and services,offering a comprehensive range of support including tender management,solution identification,and project implementation.The company's main office, located in the western region of Singapore,houses the Administration department and core server systems. Connectivity to external networks is established via an ISP leased line,with a firewall implemented on router R2 to monitor and control inbound and outbound traffic.Additionally,the main office is linked to two remote branch offices,which host the Engineering and Sales departments.
The company is in the process of deploying a wired network infrastructure designed to support up to 100% growth over the next 5 to 10 years.A logical network diagram has been provided for reference.Your task is to design and implement the network for ABC Pte Ltd based on the given specifications.Additionally,they have specified that the proposed network must be fully implemented using Cisco Packet Tracer.
Phase 1: Requirements
Logical diagram
Requirements
The company has requested that the project proposal be prepared for presentation,with the additional requirement that the proposed network be fully implemented using Cisco Packet Tracer.
Company's Requirements (Task 1-addressing)
employees (Refer to Appendix 1)in the Administration department
employees (Refer to Appendix 1)in the remote Sale Office
employees in the remote Engineering Office
Lifetime maximum of servers(Refer to Appendix 1)on a separate subnet,regardless of company growth
Use subnet address(Refer to Appendix 1)for connection to the Internet router
Use given address range(Refer to Appendix 1)for internal addressing
Use VLSM for IP addressing
Expect 100%growth of current IP requirements when determining the size of subnets
The company expects a VLSM design to be used in order to optimize IP address allocation.A table should be created to display all possible subnets that meet the company's requirements using the VLSM approach. Any subnets that are not utilized should be clearly marked within the table.The following is the header of a sample table layout designed for documenting the VLSM addressing scheme:
For each location,an additional set of tables is required.These tables assist with design and development activities and are used when configuring the routers.Create a separate table for each router at each location.
Below is a sample table header layout for documenting router parameters:
Location:
Router Name:
Company's Requirements(Task 2-Router Configuration)
Apply appropriate hostnames/passwords to all router
Apply clock rate 128000 for serial interface where applicable.
Ensure appropriate static/default route is applied to R1 and R2
Disable routing updates to appropriate devices
Company would like to use OSPF for their network.
OSPF Process ID_(Refer to Appendix 1)
DR/BDR to be applied for multi-access network
- R2 to be designated as DR
- R5 to be designated as BDR Multi area OSPF to be used
- R2,R3 and R5(Backbone area 0)
- R4(ABR-Area 0,1 and 2)
Use appropriate loopback address for router ID
Ensure network redundancy for ISP given an additional Router R7 and another ISP link.
Hello and Dead time interval for Serial interface to be updated to 20 seconds and 80 seconds respectively.
Testing of Network(Task 3)
The company specifies the following network testing and is receptive to suggestions or recommendations about other testing,as well as future network improvements.
Testing and Verifying Strategy
To provide printout of routing table(text files) for each router
To provide evidences of connectivity across different routers using "Ping"test
Recommendations for future network improvements.
