# Routing Table Dataset

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

## Routing Table Status

The routing table is organized and represented as an **RoutingTable** block:

    RoutingTable := ROUTINGTABLE-TYPE TLV-LENGTH

                       RoutingTableEntry*

                       DryHRoutingTableEntry*

## RouteTable

All routing table information in LS or HR mode is organized and represented as an **RoutingTableEntry** block.

    RoutingTableEntry := ROUTINGTABLEENTRY-TYPE TLV-LENGTH

                            Destination

                            NextHop+

    Destination := DESTINATION-TYPE TLV-LENGTH

                        Name                

    NextHop := NEXTHOP-TYPE TLV-LENGTH

                      Uri

                      Cost(Double)

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).

Also note that currently in dry run mode, HR and LS routing table are printed consecutively with no separation.

## TLV-TYPE assignments

Type                                        | Assigned value    | Assigned value (hex)

Uri                                         | 141               | 0x8D
