9tut new ccna questions.Link State AnnouncementsWhen first learning about OSPF LSAs, many people tend to be a bit intimidated by them. the output of the show ip ospf database command (the command that lists a summary of the output) is quite long. The command to view a specific LSA will list more information. The details come in the form of some sort of code, using a lot of numbers. It may look a bit messy.However, if you think about OSPF regions and region design while viewing LSAs, some of the most common types of LSAs will seem more reasonable. For example, think of an LSDB in a zone, as in the example shown in Figure 8-8. The details of the topology include the connections between routers and As it turns out, OSPF defines the first two types of LSAs,to define these specific details, as follows.Each router in the area has a router LSA.Each network that has a DR plus a DR neighbor has one network LSA.5.2 Base Content 169Next, think about subnets in other regions, as shown on the right side of Figure 8-8. Short summary information about subnets in other regions (basically just subnet IDs and masks) exists as a third type of LSA.. There is one summary LSA for each subnet ID in a different region. the next few pages discuss these three types of LSAs in more detail. table 8-4 lists some information for all three types for easy reference and study.Table 8-4 lists some information for all three types for easy reference and study.
