| 5 | 1 | Vince Lehman | ## LSAs |
| 6 | 2 | Vince Lehman | |
| 7 | All LSAs have 3 fields in common represented by an **LsaInfo** block: |
||
| 8 | 1 | Vince Lehman | |
| 9 | LsaInfo := LSA-TYPE TLV-LENGTH |
||
| 10 | OriginRouter |
||
| 11 | SequenceNumber |
||
| 12 | ExpirationPeriod? |
||
| 13 | |||
| 14 | OriginRouter := ORIGIN-ROUTER-TYPE TLV-LENGTH |
||
| 15 | Name |
||
| 16 | |||
| 17 | SequenceNumber := SEQUENCE-NUMBER-TYPE TLV-LENGTH |
||
| 18 | nonNegativeInteger |
||
| 19 | |||
| 20 | ExpirationPeriod is the remaining lifetime of an LSA or omitted if it's infinity. |
||
| 21 | |||
| 22 | ## Adjacency LSAs |
||
| 23 | |||
| 24 | 7 | Laqin Fan | All Adjacency LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/adjacencies` or '/localhost/nlsr/lsdb/adjacencies'. |
| 25 | 1 | Vince Lehman | |
| 26 | AdjacencyLsa := ADJACENCY-LSA-TYPE TLV-LENGTH |
||
| 27 | LsaInfo |
||
| 28 | Adjacency+ |
||
| 29 | |||
| 30 | Adjacency := ADJACENCY-TYPE TLV-LENGTH |
||
| 31 | Name |
||
| 32 | Uri |
||
| 33 | Cost |
||
| 34 | |||
| 35 | ## Coordinate LSAs |
||
| 36 | |||
| 37 | 7 | Laqin Fan | All Coordinate LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/coordinates` or '/localhost/nlsr/lsdb/coordinates'. |
| 38 | 1 | Vince Lehman | |
| 39 | CoordinateLsa := COORDINATE-LSA-TYPE TLV-LENGTH |
||
| 40 | LsaInfo |
||
| 41 | HyperbolicRadius |
||
| 42 | HyperbolicAngle |
||
| 43 | |||
| 44 | 4 | Vince Lehman | Double := DOUBLE-TYPE TLV-LENGTH(=8) |
| 45 | double-precision floating-point number in binary64 format as defined in IEEE 754 |
||
| 46 | |||
| 47 | 1 | Vince Lehman | |
| 48 | HyperbolicRadius := HYPERBOLIC-RADIUS-TYPE TLV-LENGTH |
||
| 49 | Double |
||
| 50 | |||
| 51 | HyperbolicAngle := HYPERBOLIC-ANGLE-TYPE TLV-LENGTH |
||
| 52 | Double |
||
| 53 | |||
| 54 | |||
| 55 | ## Name LSAs |
||
| 56 | |||
| 57 | 7 | Laqin Fan | All Name LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/names` or '/localhost/nlsr/lsdb/names'. |
| 58 | 1 | Vince Lehman | |
| 59 | NameLsa := NAME-LSA-TYPE TLV-LENGTH |
||
| 60 | LsaInfo |
||
| 61 | 6 | Vince Lehman | Name* |
| 62 | 1 | Vince Lehman | |
| 63 | 3 | Vince Lehman | ## LSDB Status |
| 64 | 1 | Vince Lehman | |
| 65 | 7 | Laqin Fan | All LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/list` or '/localhost/nlsr/lsdb/list'. |
| 66 | 1 | Vince Lehman | |
| 67 | The LSAs in the LSDB are organized and represented as an **LsdbStatus** block: |
||
| 68 | |||
| 69 | LsdbStatus := LSDB-STATUS-TYPE TLV-LENGTH |
||
| 70 | AdjacencyLsa* |
||
| 71 | CoordinateLsa* |
||
| 72 | NameLsa* |
||
