Cisco Projects

Projects during “MSc in Internetworking” from University of Technology Sydney, AUSTRALIA

Designed, implement, test, troubleshoot, document and presented a network using CISCO 2600 Routers and 2950 L-2 Switches with VLSM, Static and Default Routes, EIGRP, OSPF, VLAN, 802.1q Trunking, Inter VLAN Routing, DHCP Server, IP host lookup table, HTTP Server, TFTP Server, Access Control List. NAT/PAT and Standard, Extended & Named ACLs. Used OSPF routing, having all routers in Single Area. Loopback addresses used as the OSPF router ID in determining the Designated Router (DR).

Developed WAN network using an OSI layer two protocol “Frame Relay” (PVC and Sub-interfaces). The main focus of this project was using access-list for allowing networks that are on one end of the Frame Relay to the networks situated on the other end of Frame Relay. OSPF was used as a routing protocol.

Configured a complex network using Distribution Layer Switch as VTP Server and all other switches as clients. Configuring Native VLAN, VTP Domain, Trunk links and EtherChannel links. EIGRP as routing protocol between NAT Router and Core Layer Switch. NAT on Border Router to provide Internet access to all internal hosts. Moreover, Fast EtherChannel IEEE 802.1q Trunks between Access layer & Distribution layer switches. Inter VLAN Routing with an External Router and with Internal Route Processor. Configuring Hot Standby Router Protocol (HSRP). Also configured Protected Ports, Port Fast, BPDU Guard, Root Guard, Loop Guard, Uplink Fast and Backbone Fast.

Configured EIGRP Frame Relay Hub and Spoke – Router used as a Frame Relay Switch and Adtran Atlas 550 used as a Frame Relay Switch. OSPF Single Area, Multiple Area with Stub Areas, Totally Stubby and Not So Stubby Area Configurations, OSPF over Frame Relay, OSPF Virtual Links and Area Summarization. Redistribution between RIPv2 and OSPF, between EIGRP and OSPF, between EIGRP and IS-IS. Manipulating Administrative Distances and configured Floating Static Routes. BGP with Default Routing. Configured OSPF for IPv6, Using Manual IPv6 Tunnels. Configured 6to4 (IPv6 to IPv4) Tunnels.

Implementing BGP with Multi Area OSPF. Configured two networks in different Autonomous Systems. One Autonomous System had Multi Area OSPF and other Autonomous System acted as ISP. BGP was used for creating connection between two Autonomous Systems. Weight and Local Preferences attributes used in order to apply policy based routing for efficient routing between the two different networks.

Configured an Asynchronous Dialup Connection, PPP Interactive Mode, PPP Callback. Configured ISDN BRI, Snapshot Routing, PPP Multilink for ISDN B Channel Aggregation and ISDN PRI, ISDN using Dialer Profiles. Configured Hub and Spoke Frame Relay and Full Mesh Frame Relay with sub-interfaces. Frame Relay Router and Switch Configuration. Configured ISDN Dial Backup with Frame Relay. Using Secondary Links for On-Demand Bandwidth. Configured Dialer Backup with Dialer Profiles. Configured DDR Backup using BRI and Dialer Watch. Configured Static and Dynamic NAT, NAT Overload (PAT). Configured Router Security, AAA Authentication, Authorization, Accounting and AAA TACACS+ Server. Configured a site-to-site IPSec VPN using Pre-Shared Keys.

Other Projects

VMware familiarity, Unix OS Installation, Password recovery, System startup and log files, Controlling super user accounts, Managing Users and Groups with policies and passwords, Monitoring log files with Logwatch, Monitoring changes in system files with Tripwire, Gathering file system information and Implementing disk quota, Static Unix Networking and Network troubleshooting, Configuring a DHCP Server & Client, Configuring Domain Name System (DNS) Server and Client, Configuring Network File Server (NFS), Configuring SAMBA, Basic Mail Server configuration, Basic APACHE Web Server configuration, Security risk assessment, Backup Plans.

Designed SNMP based solution to automatically locate a “Health Monitoring Device” based on IP address which they receive from a DHCP server, using ARP Cache. Wrote the functional specification defining how a health monitoring system operates. The system is to be based on SNMP and is to utilize the capability in the various device MIBs (Management Information Base).

Configuring Cisco 1200 Access Points (APs), AP Radio Interfaces using GUI and CLI mode, AP roles, Multiple SSIDs and channel allocations, AP as a Repeater, AP Antenna setup, AP Diversity settings.

Configuring basic AP security through GUI and CLI mode, Filters on AP using IP and MAC address, WEP (Wired Equivalent Privacy) on AP and Client, AP as a repeater using WEP, LEAP/PEAP using local RADIUS Authentication, VLANs on AP, Configuring Bridge BR1310 site-to-site Wireless link using Enterprise security.

GSM infrastructure, Call Flow, PSTN & Cellular Networks components (Base Station, Mobile Switching Centre, Antennas)

Research and presented a comprehensive report on an application of Medical Sensors for Vital Signs Monitoring and Patient Tracking over Wireless Cellular Networks such as GSM, GPRS. The information collected is transferred wirelessly to a server where an intelligent decision on what assistive action is to be taken concerning the monitored health conditions.

Provided a WAP website using the NOKIA Mobile Internet Toolkit that emulates the basic functionality of the Film section of the website. The project includes WML cards, WML script input validation, Card events to ensure the effective navigation and Templates to ensure the data transfer is efficient.

Although the technological aspect was covered in this project but I did research and presented a comprehensive research report on the Social and Ethical Implications of Biometrics covering the different issues such as: - Security and privacy, cost, reducing frauds, challenges and risks of Biometrics. I also provided some suggestions how these issues can be resolved.
