In the discussion of link-state protocols, you read that every router advertises its active OSPF links to all its neighbors; you also learned about the five categories of links that the router advertises in OSPF. Recall that the five link states are:
| Type | Description |
|---|---|
| 1 | Router link state |
| 2 | Network link state |
| 3 | Summary link state (type 3) |
| 4 | Summary link state (type 4) |
| 5 | External link state |
