Task 4: Configure RIPv2 routing in Region 1 (15 marks)
- Configure all routers in Region 1 (R1, B1-R1, B2-R1,B3-R1 and ISP-R1) with RIPv2 as the dynamic routing protocol.
- Disable automatic summarization.
Task 5: Configure Static Routing between ISP Routers (5 marks)
- Implement default route on ISP-R1 router to reach Region 2.
- Configure to distribute the default static route to all RIPv2 routers.
Task 6: Configure OSPF routing in Region 2 (15 marks)
- Configure all routers in Region 2 (R2, B1-R2, B2-R2, B3-R2 and ISP-R2) with OSPF as the dynamic routing protocol, process ID 10 and routing area 0.
- Implement summary static route on ISP-R2 router to reach Region 1.
- Configure to redistribute the summary static route to all other OSPF routers.
Task 7: Verify Full Connectivity between all Devices in the Topology (10 marks)
- You should now have end-to-end connectivity. Use ping to test connectivity across the network. Each PC should be able to ping across other routers to reach the PCs and both Web Servers.
- Use commands such as “show ip route” to make sure the routes are complete.
- Troubleshoot until pings are successful.
Task 8 A: Disable Routing Updates on Appropriate Interfaces (5 marks)
- Routing updates do not need to be sent out of all the router interfaces. Disable routing updates on appropriate interfaces.
Task 8 B: Modify hello and dead time intervals (5 marks)
- Configure the hello intervals on the branch routers to 8 seconds and dead time intervals to 32 seconds.
Task 9: Calculate metric cost (5 marks)
Calculate the metric cost from Web Server 2 to one of the destination network of B3-R2 router. Submit this calculation in Microsoft Word together with Packet Tracer file.
Task 10: Documentation and interview (15 marks)
On each router, capture the following commands and output to Word or .txt files, save in hard drive for project interview, assessment and submission.
- show ip route
- show ip protocols
- show ip ospf interface (additional for R2, B1-R2, B2-R2, B3-R2)
