ccna 200 301 syllabus examples pdf to excel.. Point-to-multipoint, point-to-multipoint, part of CCNP.. Virtuallinks, virtual circuits, where two routers do not need to be directly adjacent to each other to establish an adjacency relationship, are also part of CCNP.CCNAs just need to master the configuration of OSPF in point-to-point serial lines and in multi-access Ethernet. The OSPF Hello interval varies in different network types. By default, the default Hello interval is 10 seconds on broadcast and point-to-point links; on NBMA networks it is 30 seconds. The death interval is four times the Hello interval.The router's Hello interval and death interval can be modified with the following command.Router(config)#int sl/1 Router(config-if) #ip ospf hello-interval 20 Changes the RZIQ interval to 20 seconds* Router(config-if) #ip ospf dead-interval 60 Changes the death interval to 6. seconds.2. dbd (DatabaseDescription, database status description packet)DBD is a short description of the sending router's link-state database, which can be understood as an outline or directory. The receiving router uses this information to compare with the local link-state database to check whether the link-state databases of the sending and receiving sides are synchronized.3. LSR (Link-StateRequest) The receiving router can send an LSR to request details of certain entries in the DBD of the sending router.4. LSU (Link-State Update, Link-State Update packet)LSUs are used to update OSPF routing information and reply to LSR requests. LSUs are divided into various types of LSAs (Link-StateAdvertisement), for example, type 1 LSAs are RouterLSA, type 2 LSAs are NetworkLSA, etc. The discussion of LSA types is part of the CCNP.
