250IP Routing Configuration and Management

Lsid	The Link State ID is a link state type-specific field
	containing either a Router ID or an IP address. This
	field identifies the section of the routing domain that
	is being described by the advertisement.
RouterId	The unique identifier of the originating router in the
	Autonomous System.
Sequence	This field is used to detect old or duplicate link
	state advertisements by assigning an incremental
	number to duplicate advertisements. The higher
	the sequence number, the more recent the
	advertisement.
Age	The age of the link state advertisement in seconds.
Checksum	The checksum of the complete content of the
	advertisement, excluding the Age field. This field
	is excluded so that the advertisement’s age can
	be increased without updating the checksum.
	The checksum used is the same as that used in
	ISO connectionless datagrams and is commonly
	referred to as the Fletcher checksum.
Advertisement	The entire link state advertisement including the
	header."
