||
| 19 | |||
| 20 | All Adjacency LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/adjacencies`. |
||
| 21 | |||

||
| 32 | |||
| 33 | All Coordinate LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/coordinates`. |

||
| 51 | |||
| 52 | All Name LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/names`. |

| 58 | ## LSDB Dataset |
||
| 59 | |||
| 60 | All LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/list`. |
||
| 61 | |||
| 62 | The LSAs in the LSDB are organized and represented as an **LsdbStatus** block: |
