Homelab OSPF Routing Configuration

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.
