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 | All Adjacency LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/adjacencies`. |
||
25 | |||
26 | AdjacencyLsa := ADJACENCY-LSA-TYPE TLV-LENGTH |

35 | ## Coordinate LSAs |
||
36 | |||
37 | All Coordinate LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/coordinates`. |
||
38 | |||
39 | CoordinateLsa := COORDINATE-LSA-TYPE TLV-LENGTH |

53 | |||
54 | ## Name LSAs |
||
55 | |||
56 | All Name LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/names`. |
||
57 | |||
58 | NameLsa := NAME-LSA-TYPE TLV-LENGTH |

61 | |||
62 | ## LSDB Dataset |
||
63 | |||
64 | All LSAs in the LSDB are published as a [[NFD:StatusDataset|Status Dataset]] at `/$ROUTER_NAME/lsdb/list`. |
||
65 | |||
66 | The LSAs in the LSDB are organized and represented as an **LsdbStatus** block: |
||
67 | |||
68 | LsdbStatus := LSDB-STATUS-TYPE TLV-LENGTH |
||
69 | AdjacencyLsa* |
||
70 | CoordinateLsa* |
