OSPF Framework & OSPF Packets: LSDB, LSA, Hello, DBD, LSR, LSU, LSAck

OSPF makes use of three tables: Neighbor Table, Topology Table, and a Routing Table. The Topology table in OSPF is referred to as the Link State Database (LSDB). Each entry within the topology table is referred to as a Link State Advertisement (LSA). In this video we'll unpack each of these terms. Then we'll take a look at the types of OSPF Packets: Hello Packets, DBDs, LSRs, LSUs, and LSAcks (Database Descriptors, Link State Requests, Link State Updates, and Link State Acknowledgements). These five packets are involved in every OSPF conversation.
