Why learn LSDB — Link-State Database?

Stores topology information learned by a link-state routing process.

Where it came from

Database scope and synchronization rules depend on the routing protocol.

• Memory aid (a learning cue, not the expansion): Link States become a DataBase of the network map.

Build your understanding

Work through these exercises in order. Try the task before opening a reference.

1. Without looking, expand LSDB: Link-State Database.
2. Recall this memory aid: Link States become a DataBase of the network map.
3. Explain the practical use: Stores topology information learned by a link-state routing process.
4. Explain this distinction: Database scope and synchronization rules depend on the routing protocol.
5. Identify LSDB in a device specification, architecture diagram, or system inventory.
