The Link State Advertisement header

All LSAs begin with a common 20-byte header. This header contains enough information to uniquely identify the LSA (LS type, Link State ID, and Advertising Router). Multiple instances of the LSA may exist in the routing domain at the same time. It is then necessary to determine which instance is more recent. This is accomplished by examining the LS age, LS sequence number, and LS checksum fields that are also contained in the LSA header.

link_state_type: Ospfv3LinkStateType
