The Link State Advertisement header

All link state advertisements begin with a common 20 byte header. This header contains enough information to uniquely identify the advertisement (LS type, Link State ID, and Advertising Router). Multiple instances of the link state advertisement 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 link state advertisement header.
