LSDB DataSet¶

LSDB datasets are published in the namespace /$ROUTER_NAME/lsdb/ or '/localhost/nlsr/lsdb':

LSAs¶

All LSAs have 3 fields in common represented by an LsaInfo block:

LsaInfo := LSA-TYPE TLV-LENGTH
             OriginRouter
             SequenceNumber
             ExpirationPeriod?

OriginRouter := ORIGIN-ROUTER-TYPE TLV-LENGTH
                  Name

SequenceNumber := SEQUENCE-NUMBER-TYPE TLV-LENGTH
                    nonNegativeInteger

ExpirationPeriod is the remaining lifetime of an LSA or omitted if it's infinity.

Adjacency LSAs¶

All Adjacency LSAs in the LSDB are published as a Status Dataset at /$ROUTER_NAME/lsdb/adjacencies or '/localhost/nlsr/lsdb/adjacencies'.

AdjacencyLsa := ADJACENCY-LSA-TYPE TLV-LENGTH
                  LsaInfo
                  Adjacency+

Adjacency := ADJACENCY-TYPE TLV-LENGTH
               Name
               Uri
               Cost

Coordinate LSAs¶

All Coordinate LSAs in the LSDB are published as a Status Dataset at /$ROUTER_NAME/lsdb/coordinates or '/localhost/nlsr/lsdb/coordinates'.

CoordinateLsa := COORDINATE-LSA-TYPE TLV-LENGTH
                   LsaInfo
                   HyperbolicRadius
                   HyperbolicAngle

Double := DOUBLE-TYPE TLV-LENGTH(=8)
            double-precision floating-point number in binary64 format as defined in IEEE 754


HyperbolicRadius := HYPERBOLIC-RADIUS-TYPE TLV-LENGTH
                      Double                      

HyperbolicAngle := HYPERBOLIC-ANGLE-TYPE TLV-LENGTH
                     Double

Name LSAs¶

All Name LSAs in the LSDB are published as a Status Dataset at /$ROUTER_NAME/lsdb/names or '/localhost/nlsr/lsdb/names'.

NameLsa := NAME-LSA-TYPE TLV-LENGTH
             LsaInfo
             Name*

LSDB Status¶

All LSAs in the LSDB are published as a Status Dataset at /$ROUTER_NAME/lsdb/list or '/localhost/nlsr/lsdb/list'.

The LSAs in the LSDB are organized and represented as an LsdbStatus block:

LsdbStatus := LSDB-STATUS-TYPE TLV-LENGTH
                AdjacencyLsa*
                CoordinateLsa*
                NameLsa*
