OSPF Single Area Lab

Routing

OSPF Single Area Lab

Overview

This lab demonstrates OSPF single-area configuration, including neighbor formation, route advertisement, and routing table verification.

Requirements

  • Configure IP addressing on all routers
  • Enable OSPF process on routers
  • Advertise networks in Area 0

Steps

  1. Enable OSPF process on each router
  2. Configure router IDs for identification
  3. Advertise connected networks into Area 0
  4. Verify OSPF neighbor adjacency formation

Solution

  1. Step 1: Enabled OSPF process using router ospf 1
  2. Step 2: Assigned unique router IDs for each router
  3. Step 3: Advertised networks using network commands under Area 0
  4. Step 4: Confirmed neighbor adjacency using show ip ospf neighbor
  5. Step 5: Verified routing table entries learned via OSPF

Verification

  • OSPF neighbors successfully formed
  • Routes learned and installed in routing table
  • Ping successful between remote networks
  • No adjacency issues detected

Notes

  • OSPF requires matching area IDs to form adjacency
  • Router ID must be unique in the OSPF domain
  • Hello and Dead timers must match for neighbors
