Mission 023

Engineer Briefing

In the previous mission, you learned how routers communicate using static routes.

A network administrator manually configured paths:

Router A

Destination:

192.168.20.0/24

Next Hop:

192.168.1.2

Static routing works.

However, imagine a large enterprise network:

                 Headquarters

                    Router A

                  /        \

                 /          \

          Router B          Router C

             |                  |

             |                  |

        Branch 1            Branch 2

                    |

                Router D

                    |

                Data Center

A network engineer would need to manually configure every route on every router.

Problems appear:

• More configuration work.
• Higher chance of mistakes.
• Difficult maintenance.
• Slow response when networks change.

Large networks need routers that can learn automatically.

This is the purpose of:

Dynamic Routing
