Routing Table Dataset

The routing table can be published as a 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*

Dry HR RoutingTableEntries will be present after LS RoutinTableEntries when NLSR is run in dry run mode.
In dry run mode, clients can check if a router name is repeated and assume the beginning of HR routing table entries.

RouteTable

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

RoutingTableEntry := ROUTINGTABLEENTRY-TYPE TLV-LENGTH
                        Name
                        NextHop+

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)
Double 134 0x86
Uri 141 0x8D
NextHop 143 0x8F
RoutingTable 144 0x90
RouteTableEntry 145 0x91
