This question also puzzled me for a long time, a lot of various IE also can't answer up.There are no 2 types of LSA, and I have experimented with topologies that can be drawn according to the 1 class LSA . But one thing is missing: The description of the link is bidirectional. Take point-to-point, two routers will say I connect to you, you connect to me, as follows the first class is point-to. First Class

The six main LSA types of OSPF are: the first type. router LSA. router lsa describes the link or interface connected to the physical interface of the ROUTER, and specifies the status and cost of the link. the router in each OSPF area generates the first LSA. it allows routers to know each other's link interfaces. flood
Earlier, we have introduced the establishment of adjacency relationship and the synchronization of LSDB. Through the introduction of the synchronization process, we can understand that LSDB synchronization is implemented through the interactive LSA.The content of LSA emitted by different role routers is different, this article will introduce the structure and kind of LSA message, which can help us analyze t
Because the OSPF protocol defines the types of routers, it is also necessary to define the types of various LSA advertisements.For example: A DR Router must advertise multiple access links and all routers connected to the link, while other types of routers will not need to advertise this type of information.Seven types of LSA for OSPF:1.

Seven types of LSA (link status announcement) in OSPF are also necessary to define multiple types of LSA announcements because the OSPF protocol defines multiple router types. For example, a DR router must advertise a multi-channel access link and all routers connected to this link, while other types of routersYou do not need to advertise this type of information. Seven types of
Latent Semantic Analysis (LSA) Model Learning notesLatent Semantic analysis models, implicit semantic analyses, which we often call LSA models. There's his brother pLSA and the LDA model, which we'll talk about later. These are the more classic models in NLP! Learning this model, the main summary of the three aspects: where can the LSA model be applied? The theor

1. Observe the content notification ID and link ID of each type of LSA
2. Who issued the various LSA, what is the role

Under the guidance of this idea, people have found a simple mathematical model, the input of which is a library composed of documents written in any language, and the output is a mathematical expression (vector) of the words and words in the language. The comparison between words, the relationship between words, and even the meaning of any piece of article is generated by the operation between the vectors.The concept of latent semantics is also app

Some of the disadvantages of LSA are as follows:
The newly generated matrices are poorly interpreted. For example,

(1.3452 * car + 0.2828 * truck) can
