Hello. I was hoping an elaboration can be provided as to why Type 2 LSAs are needed. I went to the Cisco Press book and it states that OSPF has to see things as Node -> Link -> Node so it uses LSA Type 2 to model this in situations when there are more than two routers on a link. My problem is with all the verbose jargon in the book. I was hoping someone a lot more knowledgeable than I am could provide a more clear elaboration as to what the Type 2 LSAs do. Thank you.
