3 | 17 | Laqin Fan | The routing table can be published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/routing-table`: |

8 | 12 | Laqin Fan | The routing table is organized and represented as an **RoutingTable** block: |
9 | 4 | Laqin Fan | |
10 | 12 | Laqin Fan | RoutingTable := ROUTINGTABLE-TYPE TLV-LENGTH |
11 | RoutingTableEntry* |
||
12 | 26 | Ashlesh Gawande | |
13 | Dry HR RoutingTableEntries will be present after LS RoutinTableEntries when NLSR is run in dry run mode. |
||
14 | In dry run mode, clients can check if a router name is repeated and assume the beginning of HR routing table entries. |

18 | 19 | Laqin Fan | All routing table information in LS or HR mode is organized and represented as an **RoutingTableEntry** block. |
19 | 1 | Laqin Fan | |
20 | RoutingTableEntry := ROUTINGTABLEENTRY-TYPE TLV-LENGTH |
||
21 | 25 | Ashlesh Gawande | Name |
22 | 19 | Laqin Fan | NextHop+ |
23 | |||
24 | NextHop := NEXTHOP-TYPE TLV-LENGTH |

25 | Uri |

26 | 22 | Laqin Fan | Cost(Double) |
27 | 19 | Laqin Fan | |
28 | 18 | Ashlesh Gawande | Note that Double is used here as HR routing costs do have floating points (However they are installed in NFD's FIB as adjusted integers). |
29 | Also note that currently in dry run mode, HR and LS routing table are printed consecutively with no separation. |
