nfirm that all routers forming a segment have established adjacencies. 5. Routing Table Verification Check route propagation: ```plaintext Router show ip route ospf ``` Ensure that OSPF routes are present and correctly propagated. 6. Troubleshooting Common Issues Neighbor adjacenc

EIGRP in Packet Tracer EIGRP configuration steps in Packet Tracer are as follows: Access the router’s CLI and enter global configuration mode. 1. Start EIGRP with `router eigrp [autonomous-system-number]`. 2. Advertise the networks using `network [network addr
