WebOSPF Type 2 LSA/Network LSA packets are generated by the OSPF Designated Router (DR) to describe all routers connected to its segment directly. Type 2 LSA is flooded between neighbors in the same OSPF area and doesn't cross the area boundary. Type 2 Network LSA is not desired if the OSPF connection is a point-to-point. WebThese contain Link State Advertisement (LSA) headers describing the content of the entire Link State Database (LSD).The contents of the DataBaseDescriptor (DBD) received by the router are compared with its own Link State Database (LSD) to check if changes or additional link-state information is available from its neighbor. WebJan 20, 2024 · By default, OSPF floods new LSAs over all interfaces in the same area, except the interface on which the LSA arrives. Some redundancy is desirable, because it ensures robust flooding.
