Project Overview
Configured a simple network topology with OSPF to ensure routers could dynamically exchange and forward traffic across the network.
Key Tasks and Accomplishments:
Topology Setup & Configuration
- Built and configured the lab topology.
- Configured OSPF on all routers, allowing them to forward traffic to any network in the topology.
Router ID and Network Configuration
- Assigned router IDs using the router-id command to ensure correct OSPF role assignment.
- Included all directly connected networks in OSPF Area 0 with appropriate network statements.
OSPF Neighbour Verification
- Verified OSPF neighbour relationships and confirmed:
- DR (Designated Router): R1 with the highest Router ID.
- BDR (Backup Designated Router): R2 with the second-highest Router ID.
Topology Change Simulation & Recovery
- Simulated a topology change by shutting down an interface on R2.
- Observed the impact on R1’s routing table and confirmed route removal.
- Restored connectivity by re-enabling the interface, validating route reappearance.
Technologies & Tools Used:
- Cisco Packet Tracer
