LSA Type
The format and function of the link state advertisement. LSA Type is 
one of the following:
• 
Area Opaque
• 
AS Opaque
• 
Link Opaque
LS ID
The link state ID identifies the piece of the routing domain that is being 
described by the advertisement. The value of the LS ID depends on the 
advertisement's LS type.
Age
The time since the link state advertisement was first originated, in 
seconds.
Sequence 
The sequence number field is a signed 32-bit integer. It is used to 
detect old and duplicate link state advertisements. The larger the 
sequence number, the more recent the advertisement.
Checksum
The checksum is used to detect data corruption of an advertisement. 
This corruption can occur while an advertisement is being flooded, or 
while it is being held in a router's memory. This field is the checksum of 
the complete contents of the advertisement, except the LS age field.
