Mission 025

Engineer Briefing

In the previous mission, you learned how OSPF allows routers to automatically discover networks and build routing tables.

You learned:

• OSPF neighbors.
• Hello packets.
• Areas.
• Cost calculation.
• Basic OSPF configuration.

However, enterprise networks require more than simply enabling OSPF.

A network engineer must understand:

• Why OSPF neighbors fail.
• How routers identify themselves.
• How OSPF controls large networks.
• How OSPF chooses leaders on shared networks.
• How to design scalable routing environments.

This mission moves from basic OSPF configuration into real network engineering.
