LSU - link-state Up , Sends specifically requested link-state records
Hello - Discovers neighbors and build adjacencies between them
DBD Checks for database synchronization between router
LSR Requests specific link-state records from router to router
LSAck - Acknowledges the other packet types

OSPF

• Link-state routing protocol - shortest path first, Edsger Dijkstra's shortest path first(SPF) algorithm
• Exchange Hello packets
• Each router uses the LSP(link state packets) database to construct a complete map of the topology and computes the best path to each destination
• Periodical updates are NOT sent
• Administrative distance 110

OSPF configuration

router(config)# router ospf 1 router(config-router)# network 172.16.10.1 0.0.0.15 area 0
router(config-router)# network 172.16.11.1 0.0.0.15 area 0
router# clear ip ospf process - vymaze ID zaznamy

router(config-if)# ip ospf hello-interval seconds
